1550-50 OD4 Bandpass Filter

Bandpass filter with a 1550 nm (± 5.0 nm) center wavelength (CWL), a 50 nm (± 5.0 nm) full-width at half-maximum (FWHM), greater than 90% transmission, and wide-range OD4 out-of-band blocking from 200 nm to 1200 nm. It is hard-coated on a 3.3 mm thick Borofloat® substrate and mounted in a standard 25 mm (+0/-0.1 mm) diameter, 5 mm (± 0.1 mm) thick anodized aluminum ring. Alluxa OD4 bandpass filters deliver superior performance and durability over traditional laminated filters. All Alluxa optical filters are hard-coated using our innovative SIRRUS™ plasma deposition process. Contact us for custom sizing.
