OVER VIEW
Hamamatsu near infrared photomultiplier tubes (NIR-PMT)
R5509-42 and -72 have newly developed photocathodes with
extended spectral response ranges to 1.4
μ
m or 1.7
μ
m
where beyond 1.1
μ
m have been the limit of conventional
photocathodes. NIR-PMTs the R5509-42 and -72 not only
have these new spectral response ranges, but also have
good features of conventional photomultiplier tubes for fast
time response and photon counting performance, which allow
weak light detection in the near infrared region. They can
solve the problems of low sensitivity and slow time response
in other conventional near infrared detectors like a germani-
um diode which is so far commonly used in this range.
FEATURES
G
Using a "low power excitation light"
allows high-precision measurement not
affected by strong excitation light.
High gain and low noise improve the detection
limit.
InAlAs/InGaAs
single quantum wells
Sample 1
Photoluminescence spectra emitted
from a sample with different InGaAs
well widths.
This data proves that intensity distrib-
ution of the spectrum corresponding
to each quantum well varies with the
excitation light power.
G
Flat response from visible to near IR
minimize spectral sensitivity correction.
The spectral response covers a wide range from
300 nm to 1.4
μ
m or 1.7
μ
m.
G
Photoluminescence from a room
temperature sample can be measured.
High sensitivity enables weak light emission
measurement.
G
Time resolved measurement in near IR
is realized.
Fast time response (Rise time: 3 ns).
