1075-1.5 OD4 Ultra Narrow Bandpass Filter

Ultra-narrowband optical interference filter with a 1075 nm center wavelength (CWL), a 1.5 nm full-width at half-maximum (FWHM), and wide-range OD4 out-of-band blocking from 700 nm to 1800 nm. This is a multi-cavity filter with transmission that is greater than 95% at 1075 nm. This unmounted ultra-narrowband filter is coated on a 5 mm thick fused silica substrate and is 34.9 mm (± 0.1 mm) in diameter. Alluxa ultra-narrow bandpass filters have the highest transmission and narrowest bandwidths currently available. And because they are hard-coated using our innovative SIRRUS™ plasma deposition process, all Alluxa optical filters are highly durable and resistant to laser damage.
