High-speed camera HiCAM
HiCAM from Lambert Instruments is a high-speed camera for applications with challenging conditions, whether very low light conditions or particularly fast-moving processes.
A 1.3-megapixel sensor captures high-resolution images at frame rates of up to 500 fps. If required by the circumstances, the resolution can even be reduced up to 2000 fps in favor of the frame rate.
Using both Gen II and Gen III amplifiers, these extremely fast slow-motion shots are possible even in low-light conditions. The amplifiers can be adapted to the respective application (UV to IR) by a number of possible photocathodes.
The HiCAM can also be used as a high-speed shutter by gating. This reduces the effective exposure time and allows the reduction of motion blur. Cooling is provided by Peltier elements and ensures an improved signal-to-noise ratio and thus optimal image quality thanks to its nearly non-existent vibrations. As an option, additional cooling with water is possible.
Recordings can either be stored internally with the HiCAM 500 model or streamed to the computer with the HiCAM 500S. The corresponding software not only controls the camera and measurement parameters, but also data processing, amplifier power or gating.
Applications
- Combustion analysis
- Plasma Physics
- Time resolved fluorescence
- LII (laser-induced incandescence) or LIF (laser-induced fluorescence)
- Microfluidics or blood flow alaysis

STAMINA
STAMINA from Lambert Instruments is, like LIFA, a complete system. However, up to nine cameras can be used simultaneously. At the same time, the user-friendly software is compatible with a wide range of cameras and offers the option of easily integrating your own cameras into the imaging system.
STAMINA can also be inversely integrated into existing setups using API (Application Programming Interface) with compatible platforms MATLAB, LabView or Python3 (64-bit).
STAMINA synchronizes recordings so that all imaging data is streamed directly to disk, making only disk space a limitation.
Almost any camera can be integrated into the STAMINA setup, both an in-house Lambert Instruments product and an existing camera.
