Achromatic Variable Beamsplitter OPV10-VIS
JCOPTIX achromatic variable beamsplitters offer 420-680 nm, 700-1000 nm, or 1100-1600 nm bands. A broadband polarizing cube and quartz achromatic half-wave plate vary linear polarization for continuous transmitted-intensity adjustment or selected splitting ratios. Broad range and preassembled modules suit holography and interferometry. Achromatic variable beamsplitter: clear aperture 10.0 mm; 30 mm cage cube mounting; three bands, 420-680 nm, 700-1000 nm, and 1100-1600 nm; Tp 90%-0.1%, Rs 99.5%-0.1%; ready to use. A cube in a 30 mm mount and quartz achromatic half-wave plate form the module, with path direction marked on top and fast axis on the plate. JCOPTIX offers 420-680 nm, 700-1000 nm, and 1100-1600 nm versions for convenient, wide-range adjustment in holography and interferometry.
