300 mW Silicon Photodiode Sensor with Ø10 mm Aperture
300 mW Silicon Photodiode Sensor with Ø10 mm Aperture
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.

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.
Frequently Asked Questions
- What does the PD300 "Background Subtraction" do?Answer
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.
- Do I need to recalibrate my instrument? How often must it be recalibrated?Answer
Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
Accessories
Customers that purchase the above items also consider the following items. Ophir-Spiricon meters and sensors include a standard manufacturers warranty for one year. Add a one year Extended Warranty to your meter or sensor, which includes one recalibration.
