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 R5509-43 is recommended for detection up to 1.35 µm, while
the R5509-73 is up to 1.7 µm.

FEATURES
GHigh sensitivity enables accurate PL (Pho-
toluminescence) measurement with a low
excitation power that could not be ob-
tained with a strong excitation.
High gain and low noise improve the detection limit.
GFlat response from visible to near IR mini-
mizes spectral sensitivity correction.
The spectral response covers a wide range from
0.3 µm to 1.4 µm or 1.7 µm.
GPhotoluminescence from a room tempera-
ture sample can be measured.
High sensitivity enables weak light emission meas-
urement.
GTime resolved measurement in near IR is re-
alized.
Fast time response (Rise time): 3 ns.
