The PD300R silicon photodiode sensor is a general purpose circular geometry laser measurement sensor with a 10 mm aperture and removable filter. Without filter, its spectral range is 350 to 1100 nm and its optical power measuring range is 500 pW to 30 mW. With filter the spectral range is 430 to 1100 nm and the power range is 2 µW to 300 mW.
350-1100 nm silicon photodiode sensor with Ø10 mm aperture
Ophir's Photodiode PD300 and PD300-1W sensors offer automatic background subtraction so the measurement is not sensitive to room light. With "filter out" (i.e. the external filter removed for low light measurements), 2 separate detector elements are visible. The beam to be measured is incident only on the outer of the 2 detectors, but background light reaches both detectors. The instrument will show the power measured by the outer detector minus that measured by the inner detector.This patented method cancels out 95% - 98% of background light under normal room conditions, even if it is constantly changing.

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