High Speed, Deep-Cooled, SWIR Imaging
The ZephIR 2.5 is a deep-cooled, SWIR camera sensitive from 850 to 2500 nm. By deep-cooling the infrared sensor, the ZephIR 2.5 is able to acquire more signals and minimize unwanted noise for a given imaging application. The extended spectral range offers scientists and engineers the possibility of acquiring a signal covering a broader wavelength spectrum, which in turn helps build better infrared detection systems. By using thermoelectric cooling, the ZephIR 2.5 doesn’t require any maintenance from a water or a liquid nitrogen chilled unit and does not suffer from the limited lifetime of Stirling mechanical coolers. This leads to greater usability and flexibility when integrating ZephIR 2.5 cameras in your own systems.
With high frame rates allowing high speed image acquisitions through USB 3.0 or cameralink, the ZephIR 2.5 is tailored for demanding industrial applications or high precision scientific experiments. Users can also choose to use Photon etc’s PHySpec camera control software or develop their own using a Python or C++ software development kit (SDK).
