PMT Module
SeekerS
is designed to keep in mind the
challenging situation where every photon
matters and you can not enhance light so
we offer sensors with enhance low light
detection capability to meet experiment
need.
Seeker S family sensor are based on P
Applications

SALIENT FEATURES
Seeker S PMT Module
PMT module has a inbuilt 28mm PMT (Socket is suitable for
most of 28mm side On PMTs with working voltage within
-200 to -1200V), a high-voltage power supply, a voltage
divider, amplifier, and if needed wavelength cut filter can also
be provided. Magnetic shield is provided to protect the pmt
from any external interference.The PMT convert light into a
electrical signal with a gain in the range of 106
to 107 which is
further processed to a more usable analog form so that it can
be observed and analyzed on oscilloscope or through DAQ
in PC.
We offer both Current/Voltage Output type PMTs as well as
Photon counting PMT modules to meet user requirements.
It comes with 2.4″ color touchscreen LCD that shows HV
and Signal Output Simultaneously so no additional toggles
are needed. The unit include internal/external high voltage
and onboard offset adjustment, BNC signal output with
selectable gain and time constant.
Optional front end optics
and Optomechanical
Adapters are available for
detector coupling
and Optomechanical
Adapters are available for

NOTE: Digital output and high
speed amplification (signal
conditioning), Gating, Cooling and
photon Counters can be provided
based on user requirement.
We also offer housing for Head
