300 mW Germanium Photodiode Sensor with Ø5 mm Aperture
300 mW Germanium Photodiode Sensor with Ø5 mm Aperture
The PD300R-IR germanium photodiode sensor is a circular geometry laser measurement sensor for the near IR. It has a 5 mm diameter aperture and a removable filter. Without filter, its spectral range is from 700 to 1800 nm and its optical power measuring range is from 5 nW to 30 mW. With filter the spectral range is 700 to 1800 nm and the power range is 2 µW to 300 mW.

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.
Effects of Incidence Angle on Measurements
In this video, you will learn to what degree a beam’s incidence angle matters, and for which sensor types this should be taken into account.
