Quartz Zero-Order Half-Wave Plate — Model HWP51-266B
Quartz Air-Spaced Zero-Order Wave Plate, Diameter 25.4 mm, Clear Aperture Ø20.0 mm, Design Wavelength 355 nm, λ/2 Retardance
Overview
Zero-order quartz half-wave plate with 1-inch mount, having a retardance of λ/2 and a clear aperture of Ø20.0 mm. The zero-order quartz half-wave plate is mounted in a 1-inch black anodized aluminum ring, fixed with glue internally and not removable. The zero-order half-wave plate with 1-inch mount has a diameter of Ø25.4 mm and a thickness of 4.8 mm, and can be mounted in a 1-inch rotation mount. The front and rear surfaces of the housing are engraved with thin lines indicating the direction of the fast axis of the wave plate, and the circumference is engraved with the wave plate model, retardance, design wavelength and other markings for easy identification.
