Quasi-optical detectors

High sensitivity in ultra-wide frequency band and room-temperature operation make Schottky-barrier di d (SBD) b d Q i i l d h l 2. Optical lens, 3. Pre-amplifier. Comparative measurements of SBD/ Golay Cell by FTIR . diode (SBD) based Quasi-optical detectors the only alternative to Golay Cell detectors for low-THz frequency region. Bias-free operation allows for system simplicity and ultra-low noise. In contrast to Golay Cell, the SBD detectors are simpler, geometrically smaller, and much faster. The last criteria makes SBD the device of choice for many applications

ACST offers a series of quasi-optical detectors operating at frequencies from 50 GHz up to beyond 2 THz.
