Request InfoOsram Opto Semiconductors Inc.SUNNYVALE, Calif., Sept. 9, 2011 — The “three in one” SFH 7773 digital sensor from Osram Opto Semiconductors combines an infrared LED emitter with proximity and ambient light sensors in one compact unit. Combined emitter and detector chips streamline smartphone design and eliminate crosstalk. The sensor facilitates installation of proximity and ambient light sensing in smartphones and similar devices by combining the functions of a digital ambient light sensor and a digital proximity sensor. It simplifies the elimination of crosstalk by combining the emitter and detector chips together – three devices...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/22/2022Line LightThe COBRA HyperSpec SWIR 2.0 LED line light from ProPhotonix Ltd. is a SWIR hyperspectral device with 11 wavelengths filling the band from 950 to 1750 nm and a peak-to-valley ratio of <1.5. ...Photonics.com 9/21/2023Widefield Stereo MicroscopeThe Model FX-3 from Titan Tool Supply Inc. is an industrial-grade widefield stereo microscope designed to facilitate various manufacturing and quality assurance remote visual inspection tasks.
