Mount diameter: Ø25.4 mm
Clear aperture: Ø10.0 mm
With 1-inch mount, non-removable
Both surfaces coated with V-type anti-reflection coating Rabs<0.25%@design wavelength

LBTEK Zero-Order Quarter-Wave Plates are temperature-insensitive and provide a retardation of λ/4, commonly used to convert linearly polarized light into circularly polarized light. When the polarization direction of linearly polarized light forms a 45° angle with the fast axis of the waveplate, the emergent light becomes circularly 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. The model number, specific retardation, and design wavelength are also engraved around the body.

The LBTEK Rotation Mount CRM-1A is commonly used for mounting optical components such as waveplates.

Quartz Air-Spaced Zero-Order Quarter-Wave Plates, clear aperture: Ø10.0 mm, with SM05 threaded mount

Optical element diameter: Ø12.7 mm
Clear aperture: Ø10.0 mm
With SM05 threaded mount, detachable
Both surfaces coated with V-type anti-reflection coating Rabs<0.25%@design wavelength

The LBTEK Zero-Order Quarter-Wave Plate is temperature-insensitive and provides a retardation of λ/4, commonly used to convert linearly polarized light into circularly 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 model number, specific retardation, and design wavelength are engraved around the body. This waveplate can be connected to other components via SM05 internal and external threads. The waveplate in the SM05 threaded mount is secured with an SM05R retaining ring and an O-ring. The unmounted waveplate can be removed using the OWR-05A wrench for standalone use, with the fast-axis direction marked by a pencil line on the side of the unmounted waveplate.

The LBTEK Rotation Mount AMMR-05A can be used to mount waveplates with SM05 threaded mounts.

Quartz Air-Spaced Zero-Order Quarter Wave Plate, Clear Aperture: Ø20.0 mm, with SM1 Threaded Mount

Optical Element Diameter: Ø25.4 mm
Clear Aperture: Ø20.0 mm
With SM1 Threaded Mount

LBTEK zero-order quarter-wave plates are temperature-insensitive and feature a retardation of λ/4, commonly used to convert linearly polarized light into circularly polarized light. The waveplate with an SM1 threaded mount is installed in an anodized SM1-8A lens sleeve. A fine line is engraved on the end face of the housing to indicate the fast axis direction of the waveplate, and the model number, retardation, and design wavelength are engraved around the body. This waveplate can be connected to other components via SM1 internal and external threads. Note: If quartz air-spaced zero-order waveplates need to operate under high-power ultraviolet conditions for extended periods, waveplates with custom stainless steel housings are recommended.

LBTEK Rotation Mount AMMR-1A can be used to install wave plates with SM1 threaded mounts.
