Request InfoGigahertz-Optik Inc.NEWBURYPORT, Mass., June 1, 2013 — Gigahertz-Optik Inc.’s new BTS256-E LED-Luxmeter light meter characterizes illuminance, color and spectral data in solid-state and other types of light sources. The meter features a Bi-Technology sensor that includes a precision photometric photodiode and diode array spectrometer. Spectral mismatch errors of the photopic sensor are compensated for on-line using the diode array’s measured spectral data. A built-in electro-optical shutter for dark-signal pixel offset compensation increases the linear dynamic range of the CMOS diode array detector. A 20-mm-diameter...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/23/2024Radiometric DetectorsThe Silux-37xx Series from Gigahertz-Optik in collaboration with Oculus Photonics and HENSOLDT Optronics GmbH are silux radiometers made to measure ambient lighting conditions in an unambiguous...Photonics Spectra February 2024 IssueCircadian Light MeterThe MSC15-CS from Gigahertz-Optik is a handheld spectral circadian stimulus light meter that helps to model circadian phototransduction in humans by measuring optical radiation in industrial and...BioPhotonics Jan/Feb 2024 IssueUV-C Germicidal Radiometer KitThe UV-C germicidal radiometer kit from Gigahertz-Optik features the X1-UV-3725 radiometer, UV-3725-4 254 nm UV-C detector, UV-37xx-Z01 80° field of view adapter, and K-UV3725-S irradiance...Photonics Spectra December 2022 IssueUV RadiometerThe Cure-Met UV radiometer from Gigahertz-Optik GmbH handles the high temperature and intense UV or blue light levels found in UV curing processes.
