Request InfoMKS Ophir, Light & MeasurementOphir Optronics Inc. has introduced the PD300-BB, a photodiode-based detector head with a flat spectral response from 400 to 1000 nm, for power measurement of broadband light sources. Its dynamic range measures from 50 pW to 8 mW of power. The thin, low-profile head has a 10 X 10-mm aperture, with response time of 0.2 s and a low noise level of ±2 pW, making it suitable for use in radiometry. It is fully compatible with the company's Orion, Nova and Laserstar displays.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueCompact Proximity SensorThe RPR-0720 from ROHM Semiconductor is a compact 2.0 mm × 1.0 mm proximity sensor for applications requiring attachment, detachment, and proximity detection.
