Since many low power lasers have powers of about 5 to 30mW, and most photodiode detectors saturate at about 2mW, the PD300
head series has been constructed with a built-in filter that enables the basic head to measure to 300mW without saturation. The PD300
and associated heads have extensive circuitry to reject both outside electromagnetic and electrostatic interference. They are fully CE
qualified.

Radiometer and Photometer Heads
In addition to photodiode heads for individual wavelengths, Ophir also supplies heads for measuring the output of broadband light
sources. The PD300-BB head has spectrally flat response from 400 to 1000nm and therefore can give the true total power of any
broadband light source in that spectral region. The PD300-CIE head has a spectral response similar to that of the human eye and can
therefore make measurements in eye response units of Lux. The PD300-CIE is designed with a small detector with the source overfilling
the detector. It measures the light intensity per unit area in units of Lux or Foot Candles.
