Photon etc ZephIR 2.5 high-speed infrared camera

The ZephIR 2.5 from Photon etc is a fully integrated HgCdTe infrared camera with a 320- x 256- pixel focal plane array (FPA) that is sensitive from 850 to 2500 nm. A four-stage TE cooler, deep cooling at -80°C, allows it to reach very low noise levels while achieving a 340 fps rate. The company says the TE cooler’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. Quantum efficiency is up to 85%.

Applications include quality control of semiconductors, material sorting, gas detection, detection of explosive liquid precursors, borehole sample analysis, solar cell characterisation or space applications.

The camera’s hardware-coded region of interest (ROI) enables the user to choose between a full frame rate of 340 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 a software development kit (SDK).

The computer interface is either CameraLink or USB 3.0. The camera measures 169 x 130 x 97.25 mm and weighs 2.6 kg.
