Photomultiplier Tubes in Side-on and End-on Housings.


Typical responsivity curves of photomultiplier tubes.

The Choices

You need to answer two questions in order to choose the appropriate PMT components to build a system:

1. What wavelength range do you need?

We have PMTs that are sensitive in the UV, as low as 160 nm, and in the NIR as high as 1100 nm (see the responsivity curves).

2. Do you want a side-on or end-on PMT?

Side-on PMTs are more economical; the end-on systems have a larger photocathode area and have a more uniform responsivity.

What Do I Need to Build a System?

To build a complete OPMTM PMT System, you need:
  • End-on or Side-on PMT
  • 70680 Side-on or 77265 End-on PMT Housing
  • 70705 PMT Power Supply
  • Oriel OPMTM (Optical Power Meter)
