L-EOS™ is an infrared push broom hyperspectral SWIR camera 0.9 to 2.5 µm. In contrast to traditional imaging techniques that capture images in only three spectral bands (red, green, and blue) per pixel, the L-EOS, a hyperspectral imaging system, captures hundreds of spectral bands stacked in each pixel, forming a hyperspectral data cube. This unique capability allows for highly detailed and comprehensive spectral analysis of the imaged objects. However, it’s worth noting that the L-EOS requires either motion from the object or the camera itself to acquire the data cube, as it creates an image by scanning one row at the time. Hyperspectral data cube provides more information than single band imaging, making it suitable for material sorting and in-depth analysis.

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 cool-ing 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.

The cut-off wavelength shifts towards the blue by ~ 7nm for every 10 °C of cooling. Schematic of a thermoelectric device where the Peltier effect is used to generate heat flow between two materials. WHITE PAPER FIG. 1. Schematic of a thermoelectric device where the Peltier effect is used to generate heat flow between two materials. 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 where the heat sink is located. TE stages are usually connected side by side and sandwiched in two insulators. Water or air cooling is typically used to dissipate the heat accumulated in this process. The temperature that can be reached by TE coolers is related to the number of stages being used. Hence, for more effective cooling, it is possible to stack several stages. This is the case of Photon etc’s SWIR sensors, where four thermoelectric stages are cascaded together to lower the temperature. With four stages, a ΔT of 120 °C can be reached. This results in a detector operating temperature of -80 °C (193 K) with proper heat extraction, at 25 °C ambient temperature. OVERVIEW OF COOLING METHODS THERMOELECTRIC COOLING
