The Bobcat-320 is a small, high performance shortwave infrared camera.
SWIR or Short-Wave Infrared imaging covers the wavelength range from 700 nm to approximately 2500 nm. When SWIR InGaAs (Indium Gallium Arsenide) sensors are used, it typically covers the range from 900 to 1700 nm.
Although light in the SWIR band is not visible to the human eye, the photons interact with objects in a similar fashion as in the visible realm (reflected light or photons – unlike thermal images, that rely on radiated photons). Therefore, SWIR images resemble visible (black and white) images: shadows occur, contrast is high and persons or objects are easily recognizable.
Initially, SWIR imagers found application in the telecommunications industry, because they are sensitive to the 1550 nm light typically used in optical fibres. Nowadays, a wide variety of applications use SWIR imaging:
Especially for night vision, SWIR imagers also offer interesting advantages, by using the “nightglow” or atmospheric glow effect. Therefore, SWIR cameras can be used under both day and starlight conditions.
Our SWIR InGaAs cameras are very small and lightweight, use very little power, and are relatively cheap (unlike other cooled cameras that can also operate in the SWIR range). Therefore, the industry finds new applications every day for system integration where cost, size and power are critical. Obviously, flexibility in terms of data and control interfaces is also important.
That is why we offer a wide variety of both cooled and uncooled SWIR cameras. In various resolutions and various framerates. All optimized for a certain application.
