The TRiCATT is a compact lens-coupled image intensifier for scientific and industrial applications. The TRiCATT is ideal for experiments that require 1) low-light level imaging, 2) ultra-short exposures through fast gating, and/or 3) frequency-domain imaging using lock-in detection.

The Lambert Instruments TRiCATT G, a successor of the II18 Image Intensifier, is a low-light-level camera attachment that can be coupled to any camera with C-mount and a 1/2", 2/3", or 1" image sensor. The TRiCATT G increases the sensitivity of the camera and enables the detection of images at a light levels as low as 10^-5 lux.

The TRiCATT G can be outfitted with spectral input sensitivities ranging from 170 nm to 900 nm wavelength, and Gen2 or Gen3 image intensifiers, to accomodate a wide variety of applications. Both sides have an adjustable C-mount, which enables universal use.

A modulated version of the TRiCATT, known as the TRiCATT M, is also available

Customization

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.

The High-speed Intensified Camera Attachment (HiCATT) is designed for use with a high-speed camera. The HiCATT increases the sensitivity of a high-speed camera and allows low-light-level imaging applications at frame rates up to 200.000 fps. The HiCATT F-mount and C-mount connections offer optimal flexibility and are available in both 18 mm and 25 mm input diameter.

The technology in the HiCATT expands the dynamic range of a high-speed camera. At low light-level input, even single photons can be detected. While at high light levels, overexposure is prevented by the use of very short gate pulses (down to 40 ns), bringing down the duty cycle of the image intensifier up to 10,000 times. Moreover, these short exposures yield sharp images of fast moving objects.

Features

For use in combination with Hi-Speed cameras operating at speeds up to 100.000 fps
Wide selection of image intensifiers (see configurations)
Up to 25mm output image diameter, matching with the larger high-speed image sensors
Standard C-mount or F-mount input and output

With the Low Jitter Digital interface (HiCATT 25D), gain and gating of the image intensifier HiCATT can be controlled by software. The Low Jitter Digital interface also supplies the DC voltages for the HiCATT high-speed camera attachment and the gating electronics. When connecting a trigger output signal from an attached high-speed camera to the Low Jitter Digital interface, gating is synchronised with the exposure period and frame rate of the high-speed camera.
