The PD300-BB-50mW radiometric sensor has a flat spectral response photdiode sensor for measuring broadband light sources. It covers the spectral range 430 - 1000nm and has a 10x10mm aperturewith swivel mount and a removable filter. Without filter its power measuring range is 50pW – 4mW. With filter the power range is 1nW - 50mW. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.

Measuring single engine energy with power sensor
Although Ophir thermal power sensors are mainly used to measure power, they can also measure single engine energy. They integrate the power flowing through the disc over time to measure energy. The typical time for disc heating and cooling is a few seconds, so these thermal sensors can only measure pulses every few seconds, so they are suitable for so-called "single" measurements.
