Waveplates

Waveplates rotate the direction of polarization (λ/2 plates) or convert linear into circular polarization and vice versa (λ/4 plates). They are made from optical grade crystalline quartz in multiple order, low order, zero order optically contacted and zero order air-spaced designs, plus dual wavelength plates for laser harmonics and achromatic quartz/MgF2 plates for broadband sources. Plates are anti-reflection coated on both sides and supplied unmounted or mounted.
