The H9797 series fluorescence detection assemblies from Hamamatsu Corp. enables simultaneous detection of multiple wavelengths for design into cell sorters, microtiter plate readers, gene scanners, laser scanning microscopes and flow cytometers. The reflection transfer-type devices use two reflective dichroic mirrors to generate eight wavelength channels and have a high signal-to-noise ratio in the NIR. The transmission-type models have compact optics and deliver four-channel detection. All models have the H9530 photomultiplier, with a spectral response of 300 to 920 nm and a gain of 3 x 106. Beam size is 1.5 mm, and filters can range from 380 to 920 nm with a 10-nm FWHM minimum.
