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 new structure ensures higher sensitivity measurements with
lower noise. 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
GNew
structure ensures lower noise.
GUsing
a "low power excitation light" al-
lows high-precision measurement not af-
fected by strong excitation light.
High gain and low noise improve the detection limit.
GFlat
response from visible to near IR mini-
mize spectral sensitivity correction.
The spectral response covers a wide range from
300 nm 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.
