Lambert Instruments Introduces Toggel: A Next-Generation Fluorescence Lifetime Imaging Camera

New FLIM camera simplifies fluorescence lifetime imaging for researchers and imaging centers by combining excellent light sensitivity with easy image acquisition and data analysis.

 

5 April 2017 - Groningen (NL) - Lambert Instruments today announced the introduction of its next-generation fluorescence lifetime imaging camera: Toggel. This new camera makes fluorescence lifetime imaging microscopy (FLIM) and fluorescence resonance energy transfer (FRET) faster and easier with its excellent light sensitivity, sharp images and fast image acquisition.

With Toggel, Lambert Instruments aims to minimize measurement duration, automate image acquisition and simplify data analysis. These factors are of great importance to many of its customers in cell biology, cancer research and high-throughput screening.

"Toggel is the result of years of research and development." says Jasper Bosch, Development Engineer at Lambert Instruments. "From the start, we have collaborated with experts in FLIM and FRET at the Netherlands Cancer Institute, the University of Amsterdam and Delft University of Technology to make sure that this new camera fits the needs of our customers."

Toggel features a unique image sensor that was designed and optimized specifically for FLIM applications. This advanced sensor contains all the functionality required for fluorescence lifetime imaging, making the Toggel camera a solid-state FLIM camera and removing the need for an image intensifier. These technological improvements enable lifetime imaging at unprecedented frame rates with the single-image fluorescence lifetime imaging microscopy (siFLIM) method.*

"We used a prototype of this camera to develop a method for acquiring quantitative lifetime images from a single exposure." says professor Kees Jalink of the Netherlands Cancer Institute. "siFLIM takes advantage of the technical capabilities of this camera and simultaneously records two 180°-phase-shifted images. This allows for video-rate lifetime imaging with minimal phototoxicity and bleaching. siFLIM is also inherently immune to artifacts stemming from rapid cellular movements and signal transients."

Other imaging modes of the camera include regular frequency-domain FLIM acquisition and time-lapse recordings. Data analysis is done automatically by the Lambert Instruments software, which instantly calculates the fluorescence lifetime and presents it to the user as a colorized overlay on the original image.

For more information about Toggel, please visit www.lambertinstruments.com/toggel or visit Lambert Instruments at booth 91 of the Focus On Microscopy conference in Bordeaux from 9-12 April.

Kick-Off Health Hub Roden

Kick-Off Health Hub Roden

Op 13 maart 2015 werd het ambitieuze project Health Hub Roden feestelijk gelanceerd. Nu, bijna een jaar later, is er veel veranderd. De verbouwing van de locatie in het voormalig pand van Cordis is gereed. Het aantal aangesloten bedrijven overtreft de prognoses ruimschoots. Tijd om dit eerste jaar feestelijk af te sluiten.

High Speed, High Standards

As sensor resolutions and frame rates increase, so does the amount of data that is recorded by digital cameras. High-speed cameras like the HiCAM Fluo record hundreds of frames per second at high resolution. This results in nearly 1.5 GB of data per second. The camera streams all this data directly to your computer over the CoaXPress interface. This is a camera industry standard that can transfer several GB/s. But there are more industry standards for imaging devices. Lambert Instruments implements these standards to ensure that our products are easy to implement.

Intensified Imaging for Combustion Research

Researchers around the world are using the HiCATT in their combustion studies. The light intensity of flames is not very high, and very short exposure times are needed to see any details. The images below show three recordings of a blue gas flame: image A is a regular recording of a blue gas flame. It shows the general shape of the flame, but the details are lost due to the long exposure time.

Image B was recorded with a high-speed camera at 1000 fps with 1 millisecond exposure time. This image shows some of the fine details of the flame shape, but it is a little dim and blurry. The high-speed camera does a decent job at preventing motion blur by having a short exposure time. But because of this short exposure time, the camera can't collect enough light to capture a detailed image.

Image C shows what a flame looks like when using a 15 microsecond exposure time. To achieve such a short exposure time but retain image detail, we used the fast electro-optical shutter function of the image intensifier. This technique is called gating, and it allows for ultra-short exposure times. During this short exposure time, the image intensifier boosts the intensity of the incoming light to retain image detail.

This unique imaging technology enables experimental investigation of combustion and flame structure. For more information about applications of image intensifier gating for combustion research please have a look at these HiCATT user publications:

Introducing the New TRiCAM

Lambert Instruments is proud to announce the next generation of its time-resolved intensified camera. The new TRiCAM is designed for scientific and industrial applications that require low-light imaging. It features a fast sensor, a high-performance image intensifier, and a redesigned aluminum enclosure.

Fast CMOS Sensor

The sensor in the new TRiCAM captures up to 160 frames per second at full resolution, and it can reach over 1000 fps at reduced resolution. Thanks to its electronic global shutter readout method, the sensor reads out all 2.3 million pixels at the same time. This prevents rolling shutter effects and ensures optimal image quality.
 

High-Performance Image Intensifier

Fiber-optically attached to the sensor is a high-performance image intensifier. This incredibly perceptive intensifier boosts the incoming light, allowing you to capture detailed images in the most challenging light conditions.

The built-in electronics offer a wide range of functionalities. Ultra-fast gating enables exposure times down to 3 nanoseconds. By precisely timing these exposures, the TRiCAM can be used for applications like time-gated luminescence and laser-induced fluorescence. With modulation frequencies up to 120 MHz, the TRiCAM is also ideal for a wide range of frequency-domain applications.
 

Redesigned Aluminum Enclosure

The aluminum enclosure of the TRiCAM has been redesigned from scratch. While remaining as compact as before, the TRiCAM can now be configured with an 18 mm intensifier or a 25 mm intensifier. It is compatible with both C-mount and F-mount input, and the standard tripod thread.
 

Machine Vision Standards

The TRiCAM is available with a USB3 or Ethernet interface. To provide optimal integration with your existing setup, it supports USB3 Vision and GigE machine vision standards.
 

Availability

The new TRiCAM is available as of today. Our experienced sales engineers are happy to assist you with choosing the right image intensifier for your application. Please contact our sales team or one of our distributors for more information.

How to Gain New Insights with Super-Slow Motion Imaging

How to Gain New Insights with Super-Slow Motion Imaging

When things move too fast, there's nothing better than a super-slow motion replay to see what's going on. The ongoing development of high-speed image sensors gives us the ability to slow down fast-moving objects and highly dynamic processes. By taking a closer look at the slow-motion footage, we can gain unprecedented insight into these phenomena.

For industrial applications like machine welding, super-slow motion video can be used for quality control or to find the cause of defects. The video below offers a detailed look at the machine-welding process.

The Lambert HS540 Series provide a versatile solution for super-slow motion imaging. With its 2.9 megapixel sensor, you record detailed videos at thousands of frames per second.

For low-light applications, the HiCAM series offers an intensified solution for super-slow motion recordings when little light is available.

Lambert Instruments Introduces New High-Speed Cameras

Lambert Instruments is proud to announce the introduction of a new line of high-speed cameras: The Lambert HS Series. The first cameras in the Lambert HS series feature a fast high-resolution sensor. The Lambert HS540M and the Lambert HS540S offer simple and efficient high-speed imaging for scientific research, R&D, machine vision and other industrial applications.

Lambert HS540M
The Lambert HS540M is a high-speed camera for research applications. It has up to 16 GB of internal storage and is ideal for scientific research and industrial R&D. After recording your data, you can review the results in our software and trim the high-speed video before exporting it to your computer.

Lambert HS540S
The Lambert HS540S is a streaming high-speed camera for industrial applications. It is designed for high-performance tasks like machine vision, quality control and wafer inspection. Instead of saving the images to internal storage, the camera streams high-speed video directly to your computer over a CoaXPress (CXP) interface. And with Power over CXP (PoCXP) the camera can be powered over the CoaXPress channels, removing the need for a dedicated power cable.

Fast High-Resolution Sensor
Both the Lambert HS540M and the HS540S feature a high-speed CMOS sensor that records full-resolution images (1696 x 1710 pixels) at 540 fps. To increase the framerate, the camera can use a smaller part of the sensor to reduce the image resolution. By doing so, it can deliver framerates of up to 170000 frames per second. Its electronic global shutter and minimum exposure time of 2 us ensure sharp images of fast-moving objects.

Digital Imaging Standards
The Lambert HS540 cameras support digital imaging standards that make it easy to integrate into an automated setup. The Generic Interface for Cameras (GenICam) offers a universal programming interface for controlling the camera settings and retrieving the recorded data. Camera characteristics are determined using the measurement procedures from the EMVA 1288 Standard. This makes specifications more transparent and easier to compare to other cameras.

Introducing a Time-Domain FLIM Solution for Widefield Microscopes

Lambert Instruments is proud to introduce a new fluorescence lifetime imaging microscopy system: The Lambert Instruments FLIM Attachment for Time-Domain imaging. The LIFA-TD offers a turn-key solution for fluorescence lifetime imaging microscopy and is compatible with every widefield fluorescence microscope. From recording the data to calculating the fluorescence lifetime, the entire measurement procedure is automated by our advanced software.

The LIFA-TD includes a camera with a built-in image intensifier, which can precisely control the exposure of the camera. With its advanced gating capabilities, the image intensifier can reduce the exposure time to 3 ns and alter the timing of the exposure in the subnanosecond range.

A pulsed laser excites the fluorophores in the sample. By using a laser with a small pulse width, the accuracy of the lifetime measurements can be optimized.

Images are recorded with our advanced software, which also processes the data to determine the fluorescence lifetime. The fluorescence lifetimes are then shown as a colorized overlay on the original image.

No More Motion Blur

High-speed cameras are great for recording highly dynamic events. Experts in ballistics research, combustion analysis and in-vivo imaging require fast cameras for their work. The high frame rates give them unprecedented insight into what happens in the blink of an eye.

But even the best high-speed cameras have their limits. In some situations even the fastest cameras are not fast enough. Objects move too fast or emit too little light to produce a crisp image. The result is a dim or blurry picture that hardly contains any useful information.

These situations call for a high-tech solution that offers extremely short exposure times or extreme light sensitivity. With an image intensifier you can use its gating feature to achieve exposure times down to 3 ns, completely eliminating motion blur. With such a short exposure time, even very fast objects can be imaged clearly. And because the image intensifier amplifies the recorded light, you don't have to worry about underexposure.

The Lambert Instruments HiCATT upgrades your high-speed camera to the next level of performance. It is compatible with any high-speed camera and all popular lens mounts. Its image intensifier component is carefully selected to match your desired frame rate and light sensitivity. Our custom software lets you control the exposure time and the gain of the HiCATT to find the right settings for your application.

Engineers and researchers around the world use the HiCATT to study bullet trajectories, combustion processes in fuel injection engines, and voltage sensitive dyes in living tissue. Find out more about HiCATT applications and technical information.

How To Freeze A Flame: Watching Combustion in Super-Slow Motion

Some things happen too fast for the human eye to see. The blades of a spinning fan, for example, look like a blur to us. They move too quickly for our eyes to see them the way we do when the fan is off.

The same thing happens when we look at a flame. It may look like a slowly waving sheet of warm light to the human eye, but in reality it is a swirling chemical process that changes faster than we can see. Even digital cameras have a hard time recording combustion processes.

The dynamic nature of the flames requires a high-speed camera that can record thousands of images per second with each one of those images recorded in a fraction of a second. But while images can be captured during those brief periods, a regular high-speed camera can’t capture enough light to produce a clear image. It’s a challenge that combustion researchers have struggled with for a long time.

Combustion cycle of a fuel injection engine.

Combustion cycle of a fuel injection engine.

The solution is a camera that is both fast and extremely sensitive to light. We combined these advanced features into one system with the HiCAM, a high-speed camera with an unparalleled light sensitivity. It records clear images in an instant and produces super-slow motion videos that accurately show the behavior of a flame. With the HiCAM, researchers are now able to quantitatively study combustion processes in combustion burners and in fuel injection engines.

Gain Control for Automation Systems

Introducing a new control unit for intensifier attachments: The gain control unit for automated systems enables full control over the gain and anode current limit of the image intensifier.

Lambert Instruments Celebrates the 10th Anniversary of the LIFA

This year marks the 10th anniversary of the LIFA. With the first Lambert Instruments FLIM Attachment (LIFA) a decade ago, we introduced an easy and fast approach to fluorescence lifetime imaging. Since then, we advanced our imaging and analysis software; we improved our hardware and made it more compact; and we added compatibility with third-party hardware. But at the heart of the LIFA experience are still the features that matter most to our users. They are using the LIFA every day, because it is the easiest and fastest system for fluorescence lifetime imaging microscopy.

Read our interview with Dr. Kees Jalink at the Netherlands Cancer Institute about his experiences with the LIFA.

Lambert Instruments Ships First LIFA to India

Lambert Instruments is proud to announce the shipment of the first LIFA to India, following our increased effort to meet the growing demand for scientific imaging equipment in Asia.

Professor Inamdar studies quantum-dot-based FRET at Karnatak University in Dharwad, India. His interest in the LIFA was sparked by its ability to quickly measure fluorescence lifetimes. "We used to do FRET measurements using fluorescence intensities," says professor Inamdar, "but with ratiometric techniques you can't measure fluorescence lifetimes. So we started looking for a FLIM system, because fluorescence lifetimes are very useful for our kind of work."

With the LIFA, Inamdar hopes to advance his research and extend it to biological applications. The LIFA is the ideal solution for such applications, because it can record a lifetime image in a matter of seconds, practically making the process a real-time experience.

Inamdar was supported by Dynotech Instruments during the purchase process. Dynotech Instruments is a leading supplier of products and solutions in the field of optics in India, including Lambert Instruments products.

From 23rd to 25th of September, Lambert Instruments and Dynotech Instruments will be at the Laser World of Photonics 2014 in Bangalore. Visit us at booth B006 in hall 3A for more information about the LIFA and our other products.
