Research Centre «Uralsemiconductor» is one of the leading companies in Russia in the field of optoelectronic industrial automation, and our products are photodetectors with high stability of parameters, optical detectors and devices, and turbidimeters. Research Centre «Uralsemiconductor» presents the results of fundamental investigations of the Ural School (the first investigations were carried out back in 1961) in the field of creating thin semiconductor films for CdPbS-, PbS-,PbSe-, PbSnSe-type photodetectors (optical operating range of from 0.3 to 6 μm ).
The most outstanding applied result is the development of films of super pure semiconductor PbS (which has no analogues in the world). This allowed us to manufacture singleor multi-element photodetectors (with range of from 0.3 to 3.3 μm), parameters’ stability of which is near to silicon transistors.
Company «RC Uralsemiconductor» is created in 1989. This is the innovational enterprise in the field of optoelectronics which develops and lets out optical gauges and devices on the basis of their own inventions (more than 100).
1. Fields of application of photodetecting devices (integration of optical elements and electronic units in one design, with thermoelectric cooling in case of need):
- aerial space equipment;
- control of any burning processes;
- fire sensors of naked flame;
- control of collectors of electric machines (sparking);
- detectors for rolling-mills;
- annunciators of heating/cooling (range from -30°C to +990°C);
- control of overheating of axle-boxes on railway;
- detection of gas leakage (hydrocarbons, ammonia, etc.).
2. Optical turbidimeters of water and annunciators of turbidity with di pping and flowing detectors (industrial, 5 base types).
3. Development and manufacturing of photodetectors, integrated photodetectors and optoelectronic devices on order. Joint venture is also possible.
