Quartz Zero-Order Quarter-Wave Plate — Model QWP12.7-1310-SP
Quartz air-spaced zero-order waveplate, diameter 12.7 mm, clear aperture 10.0 mm, design wavelength 1310 nm, retardation λ/4, mounted in SM05 standard lens tube
Overview
Quartz zero-order quarter-wave plate with SM05 threaded mount has a retardation of λ/4 and a clear aperture of Ø10.0 mm. The quartz zero-order quarter-wave plate is mounted in a black anodized SM05-8A standard lens tube and can be connected to other rotation mounts via SM05 internal and external threads. The end face of the housing is engraved with a fine line indicating the direction of the fast axis of the wave plate, and the body is engraved with the wave plate model, retardation, design wavelength, and other markings for easy identification. In the SM05 threaded mount, the wave plate is secured by an SM05R retaining ring and an O-ring, and can be removed without the holder using a wrench OWR-05A. The side of the wave plate without the holder is marked with a pencil indicating the fast axis direction.
