TRiCATT

Compact Lens-Coupled Image Intensifier

 

The TRiCATT is a compact lens-coupled image intensifier for scientific and industrial applications that require:

  • Low-light level imaging
  • Ultra-short exposures through fast gating
  • Frequency-domain imaging using lock-in detection

Any camera with C-mount and a 1/2", 2/3", or 1" image sensor is compatible with the TRiCATT. You can find the right TRiCATT for your camera with our interactive calculator.

Features

 

High resolution image intensifiers
Gen II and Gen III image intensifiers offering the world’s highest resolution and sensitivity in the UV, visible or near infrared.

Small gate widths
Gate width down to less than 3 ns (FWHM) with minimal jitter.

High gate repetition rates
Up to 300 kHz / 2.5 MHz burst.

 

Compact design
For an easy fit to your imaging or spectroscopy setup.

Overexposure protection
User-definable current limitation and optional shutter.

Easy coupling
Efficient lens coupling to any CCD and CMOS camera (up to 500 fps) with C-mount input and output.

 

Automatic Day/Night Operation
The TRiCATT G can be supplied with automatic gain and gating control enabling 24 hours day/night operation.

Relay Lens
The high quality relay lens transfers the intensified image to the image sensor of the attached camera very efficiently and without losses in resolution. If required we can provide the 0.5x relay lens with a back focal distance of 13 mm.

Camera
Along with the Image Intensifier TRiCATT Lambert Instruments can deliver different types of CCD and CMOS cameras. If you already have a camera, you can use our interactive calculator to determine which intensifier size and relay optics are best suited for your setup.

TRiCATT M

Modulated Image Intensifier Attachment

The TRiCATT M is the successor of the II18MD modulated image intensifier and is a key component in camera based/frequency-domain systems for low-light-level applications.

TRiCATT G

Gated Image Intensifier Attachment

The TRiCATT G increases the sensitivity of the camera and enables the detection of images at a light levels as low as 0.01 mlux.

Control Units


Control Units


Control units

 

The control unit contains a micro-controller, a high voltage power supply and a RF (Radio Frequency) amplifier. The control unit has a low voltage input to receive the external modulation signal. It amplifies this signal and biases it with a variable DC photocathode voltage. The control unit offers control of the MCP voltage for setting the image intensifier gain. The control unit also monitors the light output, and switches off the image intensifier when its light output becomes too high. The control unit supports modulation frequencies up to 120 MHz.

Options

Optional: Signal Generator
Instead of using an external modulation signal generator, we offer a built-in modulation signal generator as part of the control unit/power supply for frequencies up to 120 MHz.

Optional: TRiCAM
As an alternative to the lens-coupled ICCD camera (TRiCATT + CCD), we offer an ICCD camera in which the image intensifier is fiber-optically coupled to the sensor. This is the TRiCAM. This modulated intensified CCD camera is very compact and has a significantly higher gain than the lens-coupled combination as a result of the more efficient and compact fiber coupling.
