The PD300-BB radiometric sensor with swivel mount has a flat spectral response photodiode sensor for measuring broadband light sources. It covers the spectral range 430 to 1000 nm and has a 10x10 mm aperture. Its power measuring range is 50 pW to 4 mW.
The 50 mW version PD300-BB-50mW measures from 50 pW to 50 mW. The sensor comes with a removable filter and a 1.5 meter cable for connecting to a meter or PC interface.

Measuring Very Low Laser Powers with a Photodiode Sensor
In this short “Basics” video, we review in general the use of photodiode sensors for measuring very low laser powers.
How to Measure Power of Broadband Sources
This video explains how to use Ophir sensors and meters to measure the power or energy of broadband light sources such as solar radiation, flash lamps, LEDs, etc.
The PD300 series of photodiode-based sensors are calibrated with a full spectral curve using a scanning monochromator (plus a few laser "anchor points").
The wavelength ("Laser") setting tells the meter what wavelength is being used and hence what calibration factor to apply when a measurement is underway. It does not, however, physically limit the possibility of other wavelengths from entering. All light (within the sensor's specified range of course) entering the detector will be measured; the meter will apply the calibration factor meant for the selected wavelength, "thinking" that only that wavelength is present.
In other words, these sensors assume a monochromatic light source. Their relative spectral response is not flat and they are therefore not suited for broadband beams.
So, if you want to check one wavelength from a broadband source, you will need to use a wavelength filter that only passes that wavelength. Then you should set your meter to the appropriate wavelength to account for the detector's relative sensitivity.

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
