* A spectrum of solutions CD 5795 DE GASPE AVENUE, #222 MONTREAL, QUEBEC, H2S 2X3 CANADA ZephIR™ 1.7INFRARED CAMERA TECHNICAL SPECIFICATIONS The ZephIR 1.7 is a high-end, scientific grade, 640 x 512 pixels resolution, InGaAs camera that marries performance with reliability. It has extremely low noise levels, high efficiency, and a rapid frame rate compatible with an external trigger. This is made possible by a combination of state-of-the-art control electronics and a four stage thermoelectric cooler (TEC) which can maintain an operating temperature as low as -80 °C. The TEC, in turn, uses forced air cooling which requires none of the maintenance of a water or liquid nitrogen chilled unit. The ZephIR 1.7 is one of the most sensitive and dependable InGaAs cameras on the market. MAIN ADVANTAGES » Compact » Highly reliable » Long lifetime OF TEC + AIR SYSTEM » No maintenance » Low dark current » 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...
