About
The Photomultiplier Tube, model PMT-175, is a photodetector device intended for multispectral research, special purpose equipment, and gas sensors. It employs an SbKCs photocathode with a 10 mm diameter and a linear 14-dynode multiplication system to convert incident light into an amplified electrical signal. The device has an overall diameter of 22 mm and a spectral response range of 220 to 650 nm. Its photocathode luminous sensitivity is ≤50 μA/lm, with a dark current of ≤2·10-8 А. The nominal supply voltage at an anode luminous sensitivity of 100 A/lm is ≤2200 V, and the pulse rise time is 1.5 ns. The product was first released in 2005, has a guaranteed service life of 4 years, and an estimated production/delivery time of 3 months. It is not flight-qualified, but the manufacturer offers the possibility to adapt the product to customer requirements.
