Production of semiconductor optical elements for the mid-infrared spectrum

LED Microsensor NT is the world’s only producer of the full range of LEDs and photodiodes for the mid-infrared spectrum (wavelengths of 1,600–5,000 nanometers). The product is used as a unique component base for sensors of various substances in liquids, gases, and solid matter.

Sensors based on mid-infrared LEDs can identify more than 50 substances. They can perform analysis of as many as 10 components simultaneously thanks to a multicolored matrix. Their rapid response time suits them to dynamic analyses, for example, analysis on conveyor lines or in liquid flows.

The company has a team of leading Russian scientists whose experience in research and development of heterostructures for mid-infrared spectral range exceeds 15 years.
