TRICATT Lens Coupled Image Intensifier, a turn-key solution

The TRiCATT is a versatile and compact lens-coupled image intensifier designed for scientific and industrial applications requiring:

Low-Light Level Imaging
Ultra-Short Exposures via Fast Gating
Frequency-Domain Imaging Using Lock-In Detection

The TRiCATT features an 18 or 25 mm image intensifier with a highly efficient relay lens, compatible with any CCD or CMOS camera. This flexibility allows for easy integration into existing imaging systems. The TRiCATT (Time Resolved Intensified Camera Attachment) is ideal for ultra-fast imaging in both time and frequency domains.

With a wide selection of Gen II and Gen III image intensifiers, the TRiCATT provides high sensitivity down to the single photon level and optimal spectral bandwidth for various applications. Different models are available, covering a range of spectral sensitivities, phosphor types, spatial resolutions, gains, linearities, minimum gate widths, and gating frequencies, ensuring a tailored solution for your imaging needs.

For time-domain imaging, the TRiCATT is equipped with a fast gate unit (TRiCATT G40n/G2n) that enables the image intensifier to function as an electro-optical shutter. This gate unit supports repetition rates of up to 2.5 MHz in burst. Additionally, a variety of image intensifier control units offer functionalities ranging from analog gain control to full digital control, including an internal trigger generator and programmable gate trains. For frequency-domain imaging, the TRiCATT M supports gain modulation of 120 MHz (standard) and higher (external signal generator), utilizing a single-chip digital synthesizer to ensure extremely low phase noise. Any camera with a C-mount and a 1/2″, 2/3″, or 1″ image sensor is compatible with the TRiCATT, and you can easily determine the right TRiCATT model for your camera using this interactive calculator.

Features

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

Photocathodes

The photocathode is the entrance of the image intensifier. This is where the incoming photons are converted to electrons. The quantum efficiency of the photocathode material specifies how efficient this conversion is for each wavelength.

Second generation image intensifiers

Intensifier Control Software

Intensifier Control provides a user-friendly interface for adjusting the settings of your TRiCATT. Its small window size allows seamless operation alongside any image capture and control software used with your attached camera. The main window (left) displays commonly used functions, while the settings window (right) enables configuration of trigger methods and the function for the Enable connector of the Intensifier gate generator.

Image Capture Software

Capture Software

Capture simplifies intensified high-speed imaging with its unique software solution. It effectively controls and acquires recordings from up to 9 streaming intensified high-speed cameras (HICATT intensifier + Streaming Camera + Frame grabber). Compatible with popular S series Vision Research streaming cameras, as well as Silicon Software, Euresys, and Pleora frame grabbers, Capture offers seamless integration across various setups.

With Capture, you can trigger recordings precisely using Trigger Offset, trim your footage as needed, and export videos in a range of widely-supported file formats. This user-friendly software streamlines the imaging process, ensuring efficiency and flexibility in your workflow.

TRiCATT 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.
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.
