Room Temperature Optoacoustic Detector GC-1T
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.
GC-1T 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 TPX one GC-1T detectors have wider operation wavelength range spreading down to visible/UV. They can be considered as good substitute to Diamond window model as TPX has higher transmittance in THz than Diamond and surely cheaper than the latter one. So GC-1T model is only slightly expensive than GC-1P detector.
Various THz optical components such as long 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.
