Written by AnubisTTP on 2006-12-17  


The 1P41 is an end-viewing miniature phototube with a small phenolic three pin base. The tube has a spectral response of S-1 and is filled with a low pressure argon gas. According to RCA, this tube is intended for relay applications and is optimized to detect infrared light in the 800 nanometer range. This tube uses the same 3 pin socket as those used by Honeywell 113228 Purple Peeper phototubes.
