The PD300-TP is a thin profile photodiode laser measurement senso with a switchable filter feature and a 10x10mm aperture. With filter out, its spectral range is 350 - 1100nm and its power measuring range from 50pW to 3mW. With filter in, its spectral range is 400nm - 1100nm and its power range from 20μW - 1W. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.

Why does a photodiode based power sensor like PD300 have a specified "maximum pulse energy"？
Although these sensors measure the average power (CW and repetitive pulsed beam) rather than the pulse energy, the average power of the pulsed beam may be within the rated limit of the sensor, but the energy of the pulse itself is high enough to cause instantaneous saturation of the sensor. It is important to ensure that the pulse energy is also within the sensor specifications - not just the average power.
