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.

Product release: Streaming high-speed ICMOS camera

Lambert Instruments has introduced a streaming version of its HiCAM 500 intensified high-speed CMOS camera that includes a full Camera Link® interface, making it possible to directly stream 500 fps (full frame) to your computer. The streaming HiCAM can be used in a smart camera setup by combining it with an FPGA enabled framegrabber.

The first streaming HiCAM was delivered to Zarm, the center for applied space technology and microgravity of the University of Bremen in Germany. At Zarm the HiCAM is used for a combustion experiment under microgravity conditions. The experiment is prepared in the Zarm drop tower and finally performed as part of an ESA space mission in 2014. A specific mechanical design of the fiber-optic coupling was implemented to cope with the g-forces involved.

The Lambert Instruments HiCAM is a hybrid intensified CMOS camera designed for high-speed imaging and/or ultra-fast gating at low light-levels. The HiCAM is equipped with the latest Gen II and Gen III image intensifiers providing the best possible resolution and sensitivity. Applications in the life sciences include calcium imaging, fluorescence imaging and widefield fluorescence correlation spectroscopy. Applications in the engineering sciences include combustion, particle image velocimetry and laser induced fluorescence.

Mechanical shutter for HiCAM and HiCATT

Being very sensitive tools for ultra high speed imaging the HiCATT and HiCAM are often exposed to high energy radiation. Applications like combustion experiments or UV-spectroscopy in a synchrotron beamline are good examples for situations where the photocathode can be prone to harmful scattered or direct incident light. Although this is fine during the actual measurements, extended exposure to stray light or laser bundles during alignment and other activities may damage the photocathode.

To avoid fiddling with lenscaps between measurements we have added a mechanical shutter to our intensified high speed product line. The shutter is encased in a aluminum housing with a standard F-mount input that replaces the original F-mount adapter of the HiCATT or HiCAM. The back focal distance of the F-mount input is unchanged so any F-mount objective can be used. The shutter comes with a power supply and a remote shutter controller with a timer. The timer can be used to automatically close shutter after a predetermined time. The remote has a stylish and ergonomic design and a large LCD screen. The shutter can also be controlled by a external TTL signal. When purchased together with one of our digital interfaces (s, d or p option) the shutter is controlled by the software of the digital interface.
