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.

Golay 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 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.

Application:

Monitoring and control of MIR and THz radiation.

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.

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 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.

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.
