Schwabe Holding (part of Rostec Group) showcased a line of microbolometer matrix photodetectors (MB MFPU) at the "Microelectronics 2025" forum in Sirius. These are used in compact thermal imagers for industry and security systems.
The matrix photodetectors operate in the long-wavelength infrared range and use sensors that change electrical resistance under the influence of thermal radiation. Cooling is not required, which allows creating lightweight and compact thermal imagers. Three device formats are presented: 640×480 with a 17 μm pitch, 640×512 with a 12 μm pitch, and 1280×960 with a 12 μm pitch.
Thermal imaging modules based on these photodetectors provide sensitivity up to 40 mK and high image quality thanks to built-in signal processing algorithms. The development was supported by the Foundation for Advanced Research.
In addition, Schwabe showed a digital transceiver module for high-speed fiber-optic networks, an optoelectronic module for converting optical signals with a power of 50 mW, and a single-frequency semiconductor laser with distributed feedback (DFB laser) for information transmission systems via radio-photonic channels.
