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 and individually calibrated in-house and supplied from stock.
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.
