THz Detectors

Golay Cells are opto-acoustic detectors featuring:

Polarization Rotator • Operation across a wide spectral range of 0.02-20 THz
• High responsivity 104 V/W
• Wide dynamic range 100 nW - 1 mW

Operation of Golay Cells is based on measuring vibrations in a gas cell caused by THz radiation heating. These are very stable and reliable detectors that are used in numerous research labs worldwide.
