Newport Corporation    Irvine, CA 92606
Aug 23, 2012 Featuring 23 nm clear apertures, Achromatic Zero-Order Quartz-MgF2 Wave Plates consist of 2 different birefringent crystals - crystalline quartz and magnesium fluoride - each with broadband antireflection coating, in air-spaced design. Units operate in spectral wavelengths from 610-850 nm or 700-1,000 nm. Mounted in black, anodized aluminum housing for protection, wave plates maintain retardation from ±λ/50 to ±λ/100 over entire bandwidth.
