Find the right InGaAs camera for your SWIR application
Polytec offers outstanding InGaAs cameras for different applications. All listed products are completely ITAR-free and are therefore not subject to any export restrictions. Whether light and compact or particularly low-noise and fast, cooled or uncooled - we have the right camera and advise you specifically for your application.
Low-noise, high-speed recordings for real-time applications
The SWIR cameras of the C-RED series are ultra-fast, low-noise shortwave infrared cameras that can be operated with 600 frames / sec and less than 60 electron readout noise. To achieve this, a 640 x 512 InGaAs PIN photodiode detector with 15 µm pixel pitch for high resolution is integrated, which has an electronic shutter with integration pulses shorter than 5 µs.
The C-RED 2 was developed for high-end SWIR applications in low light and offers new possibilities for science, research and industry. The C-RED 2 ER offers an extended wavelength with a quantum efficiency of over 70% (from 1.4 to 2.0 µm), which enables even deeper infrared and opens up new possibilities for astronomy, life sciences and industry. The C-RED 3 was specially developed for short exposure times and is considered the fastest uncooled VGA camera for SWIR imaging. Autonomous and compact, the C-RED 3 is also available as an OEM version.
