Request InfoMKS/NewportNewport Corp. has unveiled the 1931-C and 2931-C optical power meters for measuring any type of laser, laser diode or broadband light source. The instruments can make power measurements from 10 pW to 40 W using photodiode detectors, and they can make pulsed measurements up to 20 kHz. They can store up to 250,000 data points internally and have a USB port for additional flash memory. They have an easy-to-use menu-driven interface, and they contain a large, full-color thin-film transistor LCD that can change color to accommodate various laser-safety goggles.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2024 IssueMulti-LED for WearablesThe SFH 7018 is a red/green/IR LED package from ams OSRAM that can make photoplethysmography (PPG) measurements in smart watches, wristbands, and other wearable devices.
