NIR and SWIR camerasystems

NIR cameras

InGaAs cameras have the highest quantum efficiency in the NIR. NIR cameras cover the wavelength range of 900 – 1700 nm, a range that is best suited for absorption and radiation characteristics analyses. For example synthetics may be distinguished by varying absorption bands in the NIR, and the combination with a suitable filter or spectral camera allows different sorting applications. Another application area is agricultural technology. Different materials emit differently in the NIR so pesticides or plant damages can easily be spotted and combated. In pharmaceutical applications, InGaAs camera systems recognize fillers and active agents and in photovoltaics they help analyze the photoluminescence of solar cells and the spotting of impurities in silica blocks.

Depending on the application, our InGaAs cameras are either used as NIR line scan cameras or NIR matrix cameras. Typical NIR cameras feature either 320 x 256 or 640 x 512 pixels. You may choose between USB, analog, cameraLink, GigE or even GigE Vision interfaces.

Our uncooled NIR cameras of the XS series are very popular because of their small size. They are used in a great number of applications and in a variety of configurations.

Our model Bobcat is highly estimated in the integration industry for its high resolution, small size, and the GigE vision standard.

Our models Xeva and Xeva Large are cooled InGaAs cameras with a high sensitivity and frame rate for short and long exposure times in scientific applications.

Our Cheetah camera with a high-resolution, large-format InGaAs detector has the highest frame rate.

With up to 2048 pixels, our Lynx line scan cameras feature the largest amount of pixels and the highest resolution on the market.

NIR cameras of the Xlin series are suited for detectors that go into the shortwave infrared.

SWIR cameras

Thermal imaging cameras in the shortwave infrared become more and more important. Typical applications can be found in photovoltaics, agricultural technology, laser beam profiling, the food industry, and the synthetics industry.

The shortwave infrared camera’s detector material is MCT which has to be cooled through a four-stage thermoelectric cooler. Glass may be used as material, so there are a great variety of different objectives available. At the same time an SWIR can take pictures of processes through glass windows. We offer different MCT camera versions with frame rates up to 200 full frames per second.

Within the SWIR range, we also offer MID cameras with InSb detectors (model Onca). InSb usually covers the range 1 – 5 µm. To reduce atmospheric interferences, we use cold filters in our camera systems to reduce this range to 3 – 5 µ.
