Matrix photodetectors are a large number of discrete photodetectors arranged in a single row (linear arrays) or a two-dimensional matrix.
Number of photosensitive elements in the device can be from a few tens to even hundreds of thousands discrete “pixels”. The continuous development of technology leads to an increase in the number of elements and the degree of integration.
Photodetector matrices are applied inimage transmission devices, night vision, thermal imaging cameras, etc.
By physical principles they are semiconductor light detectors, the same as discrete photodetectors types PbS and PbSe, CdHgTe or InSb.
To ensure their functionality, the cooling and thermal stabilizing are required where thermoelectric Peltier coolers (TECs) are widely used. However, substantial and additional technical requirements for thermal management are the following:
For the matrix of Photodetectors multi-stage thermoelectric coolers with large size and high cooling capacity are required.
RMT has developed and produces special series of multistage TEC cooler for matrix photodetectors.
Series of two-stage thermoelectric cooling modules with enlarged cold side and provide maximal cooling with temperature difference 95-98 °C, that allows keeping operational temperature in a range of -40...-50 °C. The cold side dimensions are up to 11х11 mm2.
To select suitable solution and the optimal TEC for an application, the supporting is available at RMT’s website. For detailed modeling and calculations the company RMT provides our customers by free software or .And for advice and assistance.
