Because the permutations are many, we don't offer complete PMT systems for the Oriel OPM™, but rather offer the components so you can “build” your own system. Here, we give you an overview of the PMT family, and offer guidance in choosing the components.

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 OPM PMT System, you need: • End-on or Side-on PMT • 70680 Side-on or 77265 End-on PMT Housing • 70705 PMT Power Supply • Oriel OPM (Optical Power Meter) • High sensitivity UV detectors • Easy to use • End-on and Side-on models
