Request InfoGigahertz-Optik Inc.NEWBURYPORT, Mass., Jan. 3, 2013 — Gigahertz-Optik Inc.’s ISS-8P-HP integrating sphere light source features uniformity equal to or better than 98% within 90% of its output port, featuring a fast high-medium-low (H-M-L) setting of intensity level using interchangeable attenuators. The quick three-setting adjustment of light level is desirable in production comparison applications. The calibration light source standard is used for photoresponse nonuniformity comparison of imaging systems and sensors. It is built around an 8-cm-diameter integrating sphere made from the company’s highly diffuse-reflective and...See full productRelated content from Photonics MediaPRODUCTSPhotonics 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...Promoted Content March 2024 IssueCENTUM® C3 and CENTUM® Energy HarvestersCENTUM® C3 is a multistage thermoelectric cooling device with the same thickness as a single-stage chip and delivers industry-leading temperature difference and cooling density.
