Request InfoDelta Optical Thin Film A/SDelta Optical Thin Film A/S has announced custom linear variable bandpass filters for midsize and full-frame CCD and CMOS sensors. The filters offer high transmission and are fully blocked in the light-sensitive wavelength range of silicon-based detectors. They allow the design of compact, robust and affordable hyperspectral imaging detectors that offer several benefits including higher aperture and transmission than gratings and prisms, short measurement time, high suppression of stray light, and an excellent signal-to-noise ratio. Applications include cancer detection, precision...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/31/2024Quad Band ProductsThe emission filter and beamsplitter quad band solutions from Delta Optical Thin Film extend the company’s offerings to up to four wavelength passbands for multispectral fluorescence...Promoted Content August 2023 IssueNotch FiltersNotch filters eliminate or block a range of wavelengths while transmitting both shorter and longer wavelengths outside of the blocked region.
