McPherson - Current to Voltage Convertor Amplifier for Operation in Vacuum - Datasheet

The new Model 671MX preamplifier is a very stable and low noise tool for converting current from Silicon photodiode detectors to a programmed output voltage. It has an integral socket to mount a McPherson VUV photodiode. They are used for the detection of UV, EUV and x-ray (wavelength range 1100 nm to .124 nm, energy range 1.13 eV to 1 keV) photons. Unlike common p-n junction diodes, the photodiodes do not have a dead region and have zero surface recombination. These devices detect the complete photon spectral rage (0.0124 nm to 1100 nm) because of their extremely thin oxide window and 100% internal quantum efficiency.
