Golay Cell is one of the most efficient detecting devices. It has excellent sensitivity at room temperature and flat optical response over a wide wavelength range.

Golay detectors are manufactured in-house and calibrated individually. Delivery includes a detector head and a power supply unit. A mount for the filters can be supplied as an option.

Various THz optical components such as low pass filters, polyethylene polarizers as well as windows, lenses, and beamsplitters from HRFZ-Si and TPX can be supplied as a useful complement for THz applications. 

For transforming an analog signal of Golay cell to a digital signal we can offer hardware-software complex. It is served for detecting, processing, and analyzing optoacousticaldetector signals. The complex consists of  a specialized software and an electronic unit connecting Golay detector with personal computer through USB interface.

Application:

Monitoring and control of MIR and THz radiation.
