Superachromatic Half-Wave Plate SAWP10H-NIR
JCOPTIX superachromatic wave plates combine multiple quartz layers and MgF₂ for excellent broadband correction and stable λ/2 retardance. Half-wave plates rotate linear polarization to control source polarization. Two operating bands, 325-1100 nm and 600-2700 nm, have a 10 mm clear aperture. Housings mark retardance, wavelength, and fast axis. Use normal incidence and avoid moving the retaining ring, since the plate itself has no physical reference mark and the fast axis would need redetermination. Mounted versions provide convenience, accurate retardance, and precise axes; contact technical support for custom specifications. Superachromatic half-wave plates: precise ultrabroadband retardance; Ø10 mm aperture; 325-1100 nm or 600-2700 nm; preinstalled housing. JCOPTIX versions cover 325-1100 nm or 600-2700 nm and rotate linear polarization. Custom 25.4 mm diameter housings are engraved with model, phase retardance, design wavelength, and fast axis for identification and convenient, precise use.
