EKSMA OPTICS offers crystal quartz and achromatic (made from crystal quartz and magnesium fluoride) retardation plates. Multiple order, low order or zero order wave plates are available of quarter and half wave retardation. Wave plates are suitable for high or low power laser applications.
Achromatic waveplates are made from two different materials: crystal quartz and magnesium fluoride with highly efficient broadband antireflection coatings in an air spaced design.
Made from high quallity optical grade crystalline quartz quarter wave and half wave retardation versions available suitable for high and low power laser applications.
