Request InfoEdmund Optics Inc.BARRINGTON, N.J., Aug. 8, 2013 — Edmund Optics’ polymer wave plates (retarders) transmit light while modifying its optical polarization state and do not attenuate, deviate or displace the beam. Available in λ/4 and λ/2 retardance, they feature a thin birefringent polymer film layered between two glass windows for increased durability. Designed to act as true zero-order wave plates, they offer stable performance over wavelength shift and wide angles of incidence. The wave plates are offered with multiple wavelengths — 405, 488, 532, 560, 633 and 650 nm — or achromatic designs, and...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2023 IssueMounted Color FiltersMounted Machine Vision Filters from Edmund Optics Inc. are color filters optimized for use with popular LEDs with ≥85% transmission and blocking capabilities.
