and EXCLUSIVE COOLERS

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

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 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).

The dedicated coolers PC176TSCE005 and PC176TSCE006 are shipped after adjusting the voltage divider circuit to provide the optimum voltage distribution ratio that best

matches the PMT.
