The DH_INSB cryogenically cooled indium antimonide detector offers the best performance to 5.5µm.
Housing a 3mm active area indium antimonide photodiode (1-5.5µm), the DH_INSB is operated in the photovoltaic mode. Using an optically chopped input, the signal generated by this detector is best measured in using the 477 trans-impedance pre-amplifier followed by the 496 DSP lock-in amplifier. Operation in the cryogenic mode offers ultimate sensitivity and low noise performance.
The mounting flange supplied with the DH_INSB is compatible with the entire range of Bentham monochromators and accessories.
