Description
The High-speed Intensified Camera Attachment (HiCATT) is designed for use with a high-speed camera. It increases the sensitivity of your camera and enables low-light imaging at frame rates up to 1 MHz (10 Mhz in burst)
The technology in the HiCATT expands the dynamic range of your high-speed camera. At low light levels, even single photons can be detected. While at high light levels, overexposure can be prevented by very short exposures (down to 3 ns). These short exposures yield sharp images of fast moving objects.
Applications
Combustion research / Hydrogen discovery
High-speed fluorescence, bioluminescence and chemiluminescence detection for in-vivo imaging
Super-slow motion combustion research for the automotive industry
Time-resolved imaging in plasma physics research
Dynamic phenomena in microscopy
Laser-Induced Fluorescence (LIF)
Time-resolved imaging of fluids for microfluidic research
Fluorescence Recovery After Photobleaching (FRAP)
Many other industrial or scientific low-light-level applications in high-speed imaging
The HiCATT is an intensifier attachment for your high-speed camera. It provides increased light sensitivity for high-speed imaging applications. In this photo, the HiCATT is attached to a Phantom Veo 410S.
Features
Optimised for your application
The HiCATT can be configured with a wide range of image intensifiers. Our experienced engineers will help you pick the right image intensifier for your application.
High-speed Imaging
The HiCATT upgrades your high-speed camera to the next level of performance. It boosts the intensity of incoming light at speeds up to 1,000,000 fps.
Ultra-short exposures
The gated image intensifier enables exposure times down to 3 ns. At such short exposure times, motion blur is eliminated completely to ensure sharp images.
50% QE high-sensitivity intensifiers
You can choose from a wide variety of high-sensitivity image intensifiers to match the spectral needs of your application.
Rotating camera mount
Safe and easy camera coupling keeping the HiCATT and the camera in their intended orientation.
Match my camera
The relay optics of HiCATT and TRiCATT project the output of the image intensifier onto the sensor of your camera. This calculator helps you determine the optimal configuration of image intensifer diameter and relay optics for your camera and application.
Image Intensifiers
An image intensifier boosts the intensity of the incoming light. By converting photons to electrons and back to photons, the light intensity can be increased significantly. Scroll down for more information about how this works.
Another feature of an image intensifier is that it can act as an ultra-fast shutter. The photocathode can be switched between on and off in a matter of nanoseconds.
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.
Phosphors
The output of the image intensifier contains a layer of phosphorescent material. Upon impact of an electron, the phosphor screen will emit light. Depending on the type of phosphor, the intensity of the emitted light will decrease faster.
