This document describes the features and characteristics of the R5900U-L16 and H7260 series products, including high cathode sensitivity, high speed response, and multi-channel linear array applications.
The R5900U-L16 and H7260 series are linear‑array multianode photomultiplier tubes (PMTs) offered by Hamamatsu. They provide high cathode sensitivity, 0.8 mm channel pitch, and fast response for applications such as biomedical fluorescence detection, laser scanning, spectroscopy, and environmental monitoring.
The document lists detailed specifications (channel count, spectral response, rise time, supply voltage), maximum ratings, mechanical drawings, and safety warnings for high‑voltage operation. Accessories such as sockets and cable assemblies are also described.
| Channel Pitch | 0.8 mm |
|---|---|
| Number of Channels | 16 (R5900U-L16) / 32 (H7260) |
| Spectral Response Range | 300 nm to 650 nm (typical) |
| Rise Time | 0.6 ns typ. |
| Supply Voltage | 800 V |
The tubes have high cathode sensitivity with a luminous efficiency of 250 LLA/lm typ.
The R5900U-L16 series operates from –30 °C to +50 °C.
Extreme safety care must be taken because the product operates at high voltage potential.
