Optical Sensor with Housing Module (SEEKER)


PMT - Module

SEEKER provides a compact housing solution for photomultiplier tubes (PMTs), Photodiodes, Avalanche Photodidode, PIN Photodiode.

 

Photomultiplier Tube with Housing, Model : SEEKER-PMT-V1

New Age Instrument can supply a range of photomultiplier housings which incorporates the Photomultiplier tube, socket, voltage divider, electrostatic magnetic shielding, and connectors. High Voltage Power Supply also required for  voltage driven units designed to provide low noise and high stability HV to get the best out of your photomultiplier application.

Our PMT housing have following features:

  • Externally control high voltage to the PMT
  • BNC signal output.
  • Adjustable Gain control
  • LCD display for High voltage and output signal.
  • Remove the effect of dark currant and stray light.
  • Switchable Time constant

 

Application:

  • Spectroscopy & microscopy
  • Semiconductor inspection
  • Biotechnology
  • Pollution monitoring
  • Medical applications
  • Radiation measurement
  • Industrial measurement
