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.

Due to polyethylene window exchange to Diamond one, GC-1D detectors have wider operation wavelength range spreading down to visible. They are usually used when someone needs not THz and VIS ranges only but MIR also. GC-1D model is a bit more expensive than GC-1T detector. 
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 optoacoustical detector signals. The complex consists of  a specialized software and an electronic unit connecting Golay detector with personal computer through USB interface.

Monitoring and control VIS-THz radiation.
