Hamamatsu Corp. designed the H7260 multianode PMT with high-speed response and low crosstalk. Suited for multichannel chemiluminescence and fluorescence applications, the device employs a metal-channel dynode that reduces its size and increases the speed of operation. It comprises a 32-channel linear array with a 0.8 3 7-mm2 anode with a 1-mm channel pitch. It operates from 185 to 650 nm, has a peak response at 420 nm and crosstalk of 3%. Cathode sensitivity is 70 µA/lm and anode pulse rise time is 0.6 ns.
