Quartz Zero-Order Half-Wave Plate — Model HWP51-355B
Quartz air-spaced zero-order waveplate, diameter 50.8 mm, clear aperture 45.0 mm, design wavelength 355 nm, retardation λ/2
Overview
Quartz zero-order half-wave plate, featuring λ/2 retardance and a clear aperture of Ø45.0 mm. The quartz zero-order half-wave plate is installed in a two-inch black anodized aluminum ring, fixed internally with glue and not removable. The zero-order half-wave plate with a two-inch mount has a diameter of Ø50.8 mm and a thickness of 4.8 mm, and can be mounted in a two-inch rotation mount. Fine lines indicating the fast axis direction of the wave plate are engraved on the front and back surfaces of the housing, and the model, retardance, and design wavelength are engraved around the housing for easy identification.
