Request InfoTRIOPTICS GmbHThe ImageMaster HR camera-based modulation transfer function measurement system from Trioptics GmbH now has a standard exchangeable measurement head. Within minutes, the longwave infrared measurement head can be detached and replaced with a visible head. The instrument can be configured for testing optical systems in either visible or infrared regions, and it features on- and off-axis up to ±90°, a clear aperture up to 80 mm and an object at infinity. The visible measurement head can be used for digital camera and mobile phone visual applications.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/5/2022Optical Testing ProjectorThe Meridian® Sol-55 projector from Optikos Corp. provides illumination through a high-intensity white LED, which can be remotely controlled for high dynamic range measurements in automotive...BioPhotonics Sep/Oct 2022 IssueMicrospectrophotometerThe FLEX PRO™ UV-VIS-NIR microspectrophotometer from CRAIC Technologies is a multifunctional tool able to acquire microscale images and spectra from the deep UV to the NIR.
