R6094 Product Overview
The Hamamatsu R6094 is a head-on photomultiplier tube (PMT) with a 28 mm diameter and a bialkali photocathode. It features an effective light-receiving area of 25 mm in diameter and a spectral response range of 300nm to 650nm. Adopting a borosilicate glass window and an 11-stage dynode structure of box-grid and linear focusing type, this PMT delivers high gain, low dark current, fast time response and excellent photoelectric conversion performance, ideal for high-precision optical detection such as weak photon detection, radiation detection and scintillation counting.
