Request InfoPhoton etc.The imaging Bragg tunable filter from Photon etc. inc. is a family of hyperspectral imaging sensors that can acquire monochromatic images at any wavelength in the ultraviolet, visible and near-infrared spectral regions. Based on volume Bragg grating techniques, the imaging technology provides optical bandpasses from 0.25 to 100 nm between 350 nm and 2.5 μm wavelengths, and up to 90% unpolarized. The sensors are suitable for Raman imaging, biomedical imaging and remote sensing, and they are offered in laboratory and field-portable versions.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...Photonics Spectra July 2023 IssueLaser Scanning Measurement SystemThe 3DS3000, a modular 3D laser scanning measurement and inspection system from Bold Laser Automation Inc. is designed for quality assurance processes.
