Established in 2011 in St. Petersburg, Polarlight Limited Liability Company specializes in the development of spectral ellipsomers - high-tech optical devices for measuring the properties of the material, such as: composition, roughness, width, porosity and so on. Such measurements are necessary in the mass production of solar cells, chips and microprocessors, displays. The device is in demand in industry, for example, for the production of semiconductors, as well as for research purposes related to telecommunications, optics, large data storage, chemistry, biology, organics.

The product line also includes stepper motor control modules, DC amplifiers and other instrumentation. Devices are intended, among other things, for measuring parameters of ultrafine structures and surfaces and optical properties of semiconductors.

The modules assume automatic data acquisition, therefore they are intended for laboratories and experimental stands. Advanced stepper motor control systems are used for chip machines, robots and production lines.
