ALIZÉ™ 1.7 InGaAs cameras, NIR / SWIR
NIR imaging with this versatile InGaAs camera
The Alizé 1.7 is a high-end, scientific grade, 640 x 512 pixels resolution, InGaAs camera that marries performance with reliability. It has 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 -50 °C. The TEC, in turn, uses forced air cooling which requires none of the maintenance of a water or liquid nitrogen chilled unit.
The Alizé 1.7 is amongst the most cost-effective high-end InGaAs cameras on the market.

WHITE PAPER - COOLING SWIR SENSORS
AN OVERVIEW
By Simon Lessard and Laura-Isabelle Dion-Bertrand
Dark current is a critical parameter when one is looking to acquire a scientific imaging camera, especially in the short-wave infrared (SWIR) region. Very careful attention must be paid to the cooling method used to optimize this parameter. Multiple cooling technologies are available, each having certain benefits and drawbacks. In its new ZephIR line of SWIR cameras, Photon etc. uses a four-stage thermoelectric (TE4) air-cooled system to enhance the sensitivity of its imaging sensors. In this white paper, a short introduction to thermoelectric (TE) cooling is presented, as well as a comparison with other available cooling methods.
