MCT camera for eSWIR imaging
The ZephIR 2.5 is a fully integrated HgCdTe camera with a 320 x 256 pixels focal plane array (FPA) sensitive from 850 to 2500 nm. The camera provides low noise detection and easy operation. This is in large part due to a four stages thermoelectric cooler (TEC) which can maintain operating temperature as low as -80 °C. The TEC’s forced air heat dissipation requires none of the maintenance of a water or liquid nitrogen chilled unit and does not suffer from the limited lifetime of Stirling mechanical coolers.
The camera’s hardware coded region-of-interest (ROI) enables the user to choose between a full-frame rate of 340 frames per second (fps) and a windowed rate of up to 3000 fps. Users can also choose to use Photon etc’s PHySpec camera control software or develop their own using an extensive software development kit (SDK).

IR VIVO Guided Tour
IR VIVO is an infrared multispectral imager for small animal studies. This system benefits from reduced light scattering, absorption and auto-fluorescence by using a detection system in the near and short-wave infrared. Visualize your biomarkers in vivo and in real-time with optimized contrast resolution and sensitivity. IR VIVO takes advantage of the most recent developments in SWIR imaging with an ultra-low-noise InGaAs camera (Alizé 1.7 or ZephIR 1.7), novel homogeneous illumination and powerful analytical software to provide an unprecedented combination of fast, high resolution and deep imaging.
