Request InfoMKS/NewportNewport Corp. has expanded its line of wave plate offerings with the introduction of achromatic quartz-magnesium fluoride (MgF2) zero-order types. They are available in three wavelength ranges -- 400 to 700 nm, 700 to 1000 nm and 1000 to 1600 nm -- with retardation maintained from ±λ/50 to ±λ/100 over the full bandwidth. The company says that the wave plates' air-spaced construction results in a higher damage threshold than can be achieved with achromatic polymer film plates. They are suitable for use in general research applications involving optics or lasers.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra November 2022 IssueMicro-LED DevicesMICLEDI Microdisplays BV has announced microLED devices with integrated micro-lenses for pixel level beam shaping, manufactured in a 300-mm manufacturing flow.
