Achromatic waveplates are made from two different materials: crystal quartz and magnesium fluoride with highly efficient broadband antireflection coatings in an air spaced design.

Retardation tolerance of our achromatic waveplates is better than λ/100 over the entire wavelength range. The flat response of these waveplates is ideal for use with tunable lasers,multiple laser-line systems and other broad spectrum sources.

Our achromatic waveplates are available for four wavelength ranges:VIS (450-680nm), NIR (700-1000nm), 950-1300, nm 1200-1650 nm. The waveplates are provided in a black anodized aluminum housing.
