* A spectrum of solutions CD 5795 DE GASPE AVENUE, #222 MONTREAL, QUEBEC, H2S 2X3 CANADA ZephIR™ 2.5INFRARED CAMERA TECHNICAL SPECIFICATIONS 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 4000 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). MAIN ADVANTAGES OF TEC + AIR SYSTEM » Highly reliable » Low dark current » Long lifetime » Low readout noise © 12-2023 Photon etc. Inc. All rights reserved.

WHITE PAPER OVERVIEW OF COOLING METHODS THERMOELECTRIC COOLING Thermoelectric (TE) stages are solid-state devices composed of two differents faces. Those stages uses Peltier effect to generate a temperature difference between the two faces. Semiconductors with different electron densities, n-type and p-type (see FIG. 1), are placed in series and connected with a conducting material on each side. The passage of an electrical current through the junction induces a heat flow from one face to the other, creating a cold and a hot side. The cold face absorbs heat which is carried to the other side...
