Room Temperature Optoacoustic Detector GC-1P (GOLAY CELL)
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-1P 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 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. Please find relevant brochures on our web-site.
Application:
Monitoring and control of MIR and THz radiation.
