  • PH Series Photodetectors

Gentec Electro-Optics Inc.Request Info
The new PH series photodetectors are a big step forward in low-power laser measurement. They can extend your laser power measurement capability to the picowatt range. The PH series covers a spectral range between 200 nm and 1.8 microns. We offer three models to best match your application: silicon, ultraviolet(UV)-enhanced silicon and germanium. The silicon photo detectors are the best choice for typical low-power CW lasers from 300 to 1100 nm. They provide a generous aperture for laser beams to 10 mm in diameter. The silicon-UV photo detectors are perfectly suited for low-power CW lasers working at shorter wavelengths. They are sensitive down to 200 nm. For longer wavelengths, our germanium photo detectors are a nice solution between 0.8 and 1.8 microns for laser beams up to 9 mm in diameter. Furthermore, we offer two attenuators to extend the performance of the photo detectors to higher measurable powers. More precisely, the transmission of the OD-1 attenuator is 10 percent, and the transmission of the OD-2 attenuator is 1 percent. Our threaded apertures allow you to install filters, attenuators, fiber optic adapters or other optics, according to your needs.
