Request InfoGentec-EO USA Inc.Spectrum Detector Inc. has developed a family of analog and digital radiometric detector instruments to measure radiant flux from picowatts to watts, DC to 10 MHz, and UV to far-IR. The optical front-end and power supply components can be used with any one of the three detector module choices: pyroelectric, silicon or germanium. The analog models operate on 9-V batteries or on DC wall power, whereas the digital models draw power from a USB connection. Applications software is included.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/20/2022Depth Perception SoftwareEos Robust Depth Perception Software from Algolux Inc. is an expanded artificial intelligence software that delivers dense depth estimation and perception to increase the safety of passenger and...Photonics Spectra March 2024 IssueGlobal-Shutter Image SensorSTMicroelectronics’ global-shutter image sensor for smart computer vision can be used in AR/VR, personal and industrial robotics, drones, barcodes, biometrics and gestures, and embedded vision...Photonics.com 8/24/2022Digital Output EncodersNisshinbo Micro Devices Inc.’s NJL5821R and NJL5822R two-phase digital output encoders with optical reflection have been announced by MACNICA ATD Europe GmbH and are suited for detecting...Photonics.com 6/22/2023Broadband UV PhotodiodesSilicon Carbide (SiC) Broadband UV Photodiodes from Advanced Photonix are designed for UV source monitoring.
