當前位置：> 供求商機> Alluxa 1571.91-0.45 OD6 Ultra Narrow Bandpass Filter
Ultra-narrowband optical interference filter with a 1571.91 nm center wavelength (CWL), a 0.45 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 800 nm to 1800 nm. This is a multi-cavity filter with transmission that is greater than 85% at 1571.91 nm. This unmounted ultra-narrowband filter is coated on a 5 mm thick fused silica substrate and is 38.1 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.
