Request InfoThorlabs Inc.Thorlabs Inc.'s achromatic wave plates are zero-order retarders that use two birefringent materials, crystalline quartz and magnesium fluoride, to balance dispersion and to provide a nominally flat spectral response. Each wave plate is computer-designed and optimized for minimum root mean square retardance error over a broad spectral range. They are air-spaced, have antireflection coatings on all surfaces for low insertion loss, and can handle high optical powers. Quarter and half versions are available. Surface quality is 40-20 scratch-dig, transmitted wavefront error is <λ/4, and...See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase July 2023 IssueDual-Band Infrared AR CoatingsInfrared imaging systems require simultaneous performance MWIR (midwave, typically 3 to 5 μm) and LWIR (longwave, typically 8 to 12 or 7.5 to 13.5 μm) spectral bands.
