Hamamatsu near infrared photomultiplier tubes (NIR-PMT) R5509-
43 and -73 have photocathodes with extended spectral response
ranges to 1.4
碌m
or 1.7
碌m
where beyond 1.1
碌m
have been the
limit of conventional photocathodes.
The R5509-43 is recommended for detection up to 1.35
碌m,
while
the R5509-73 is up to 1.7
碌m.
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
碌m
to 1.4
碌m
or 1.7
碌m.
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.
