Golay Cells
1. Golay Cell GC-1P
Golay Detector with HDPE Window  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.

2.Golay Cell GC-1T
Golay Detector with TPX WindowGolay 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. Application: Monitoring and control UV-NIR and THz radiation. Technical specification: | Diameter of entrance cone, mm: | 11.0 | | Diameter of entrance window, mm: | 6.0 | | Material of entrance window: | Polymethylpentene (TPX) | | Operating wavelength range, μm: | 0.3 ÷ 6.5 & 13 ÷ 8000 | | Recommended detected power, W, up to: | 1 x 10-5 | | Optimum modulation frequency, Hz: | 15 ± 5 | Noise-equivalent power @ 20Hz:

3. Golay Cell GC-1D
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.
