描述 Description

OVER VIEW
Hamamatsu near infrared photomultiplier tubes (NIR-PMT) R5509-43 and -73 have photocathodes with extended spectral response ranges to 1.4 µm or 1.7 µm where beyond 1.1 µm have been the limit of conventional photocathodes. The new structure ensures higher sensitivity measurements with lower noise. The R5509-43 is recommended for detection up to 1.35 µm, while the R5509-73 is up to 1.7 µm.FEATURES
●New structure ensures lower noise.
●Using a \"low power excitation light\" allows high-precision measurement not af fected by strong excitation light. High gain and low noise improve the detection limit.
●Flat response from visible to near IR minimize spectral sensitivity correction.
The spectral response covers a wide range from 300 nm to 1.4 µm or 1.7 µm.
●Photoluminescence from a room temperature sample can be measured.
High sensitivity enables weak light emission measurement.
●Time resolved measurement in near IR is realized.
Fast time response (Rise time: 3 ns).
