Golay Cell GC-1T
Golay Detector with Diamond Window
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.
Application:
Monitoring and control VIS-THz radiation.
