The LBTEK Zero-Order Half-Wave Plate is temperature-insensitive and provides a retardation of λ/2, commonly used for rotating the polarization direction of linearly polarized light. The waveplate, with an SM05 threaded mount, is housed in a black anodized SM05-8A lens tube, with a fine line engraved on the end face indicating the fast axis direction of the waveplate. The body is engraved with the waveplate model, specific retardation and design wavelength. This waveplate can be connected to other components using SM05 internal or external threads. The waveplate in the SM05 threaded mount is secured with an SM05R retaining ring and an O-ring. With the fast axis direction marked by a pencil line on the side of the unmounted waveplate, the unmounted waveplate can be removed and used separately using the OWR-05A spanner wrench.

The LBTEK Zero-Order Half-Wave Plates are temperature-insensitive and provide a retardation of λ/2, commonly used for rotating the polarization direction of linearly polarized light. All LBTEK waveplates are mounted in a black anodized aluminum ring, with fine lines engraved on the front and rear surfaces of the housing to indicate the fast axis direction of the waveplate. The model number, specific retardation and design wavelength are engraved around the body.
