BRIDGEWATER, N.J., Sept. 20, 2011 — Hamamatsu Corp. has released the H11451 series linear array photomultiplier tube (PMT) modules.
The detectors offer high cathode sensitivity, high gain and high-speed response, with fast rise time and a narrow transit time spread. They contain a multichannel PMT along with a preamplifier and a high-voltage power supply circuit. Applications range from biomedical fluorescence to laser scanning detection to analysis including spectroscopy and environmental monitoring.
The series features eight channels in a linear format, with each channel’s photosensitive area measuring 2 × 2.5 mm. The modules are characterized by good anode uniformity, low crosstalk and a rise time of 0.7 ns. Two spectral response ranges are available: 300 to 880 nm (peak at 420 nm) and 300 to 920 nm (peak at 630 nm).
The H11459 series features 16 linear channels. Each channel’s photosensitive area measures 0.8 × 16 mm. The H11460 series features 32 channels in a linear format with a 0.8 × 7-mm photosensitive area per channel. Both series produce a rise time of 0.6 ns and a transit time spread of 0.18 ns FWHM. For both series, there are five spectral response ranges from which to choose: 185 to 650 nm, 185 to 880 nm, 300 to 650 nm, 300 to 880 nm and 300 to 920 nm.
