11PH series silicon photodetectors provide a generous aperture for laser beams up to 10 mm in diameter. The threaded aperture allows you to install filters, attenuators, fiber optic adapters or other optics that suit your specific needs. All of the detectors have a NIST traceable calibration and Personal wavelength correction™. This is the choice for typical low power CW lasers from 210 to 1650 nm. To extend the performance of the photo detectors to higher measurable powers you can select one of our attenuators. The transmission of the OD1 is 10% and the transmission of the OD2 is 1%. When bought together, the detector is calibrated with and without the attenuator.
