Overview
Gaolai detector is one of the most effective terahertz detection devices and is a classic non cooled, non selective detector. This type of detector can operate at room temperature, with excellent sensitivity at room temperature, flat optical response over a wide wavelength range, and advantages such as small size, high sensitivity, high efficiency, and wide spectral range. It is widely used in the research of IR&THz radiation sources and detectors.

Product Introduction:
Gaolai detector is one of the most effective terahertz detection devices and is a classic non cooled, non selective detector. This type of detector can operate at room temperature, with excellent sensitivity at room temperature, flat optical response over a wide wavelength range, and advantages such as small size, high sensitivity, high efficiency, and wide spectral range. It is widely used inIR & THzIn the research of radiation sources and detectors.
Product principle:
Golay cellIt is a type of optical energy detector, which operates on the principle of photoacoustic conversion. Terahertz radiation is irradiated onto the crystal of the probe, generating corresponding phonon vibrations. The vibrations then generate thermal energy, which is converted into electrical signals by a thermoelectric converter. The device consists of a probe (shown in black) and a power supply (shown in silver).
By receiving terahertz radiation through a probe and converting it into a thermoelectric signal, the pulse energy can be sensitively detected, and the signal can be obtained byBNCOutput the interface to the oscilloscope for reading.
