This single element detector is effective in sensing wavelengths between 1000nm and 4500nm. This unit is a high performance photoconductor receiver operated at ambient temperature with a dual gain FET input transimpedence amplifier. Please note that it is available in various sensor area sizes and has an available thermo-electric cooler for lower dark current and improved signal to noise. The output is an analog signal available through a BNC connector at the back of the detector housing. Since the signal is analog, an optional 12-bit and 16-bit data acquisition system and software is available to digitize its output into a computer. A DC power supply for this detector (sold separately) is also required. This detector is designed for use with scanning monochromators to capture the intensity of one wavelength at a time. An optional mount allows it to mate to any Sciencetech scanning monochromators. Sciencetech can also provide an optional custom mount for mating to non-Sciencetech monochromators and spectrographs. The PD/AMP is a AC coupled dual gain system. Care should be taken in shielding the unit from stray light during operation to prevent saturation of the amplifier (and potential failure).
This detector also comes in a TE version (SC-PBSE20-TE) which uses SCI-PS-TC-1 Power Supply.
