The PH Photo Detector Family
Gentec-EO offers a series of photo detectors that can extend your laser power measurement capability down to the picowatt range. We have a solution for your low power measurements for wavelengths from 200 nm to 1.65 micron. You have 3 models to choose from: silicon, UV-enhanced silicon and germanium. Our photo detectors also come with a wavelength selection in 1nm steps when used with our SOLOs, P-LINK and UNO monitors.
Silicon
This is the choice for typical low power CW lasers from 300 to 1100 nm. Make measurements down to 600 pW and up to 0.75 W with an OD-2 attenuator.
Silicon-UV
For low power CW lasers working at shorter wavelengths we offer this photo detector sensitive down to 200 nm. Maximum power with OD-2 attenuator is 30 mW. Other performance characteristics are similar to the regular silicon detector.
Germanium
For longer wavelengths, our germanium photo detector is a nice solution between 0.8 and 1.65 microns for laser beams up to 5 mm in diameter. With the attenuator it will go to 0.5 W. A 10 mm aperture is also available upon special request.
Attenuators
To extend the performance of the photo detectors to higher measurable powers you can select one of our attenuators. The transmission of the OD-1 is 10% and the transmission of the OD-2 is 1%.
