4Lasers provide mounted crystalline quartz zero-order compensated, air-spaced half-wave and quarter-wave retardance waveplates designed for a particular wavelength in the range of 257 - 1550 nm. Air-spaced construction enables these waveplates to be used for high-power applications, while zero-order design features lower temperature and wavelength dependence compared to low and multiple order waveplates.

Main features

■ Zero-order compensated, air-spaced design

■ True first order (FO), optically bonded on UVFS plate waveplates for high power UV application

■ Wide quarter and half waveplate selection

■ Mounted in ø25,4 x 6 mm black anodized metal mount

■ ø18 mm clear aperture

■ Antireflective coatings (R<0,15%) on each surface

■ Custom size, operating wavelength, and retardation available upon request
