精密控制用的Flat-topAlluxa

Alluxa（Flat-top）片具有的截至陡度，深度截至和正方形的光譜形狀

Flat-top,超窄的帶通濾波器特別設計，在整個通帶中有極陡的邊緣和高透過率。這個正方形的光譜形狀可以達到0.1 nm的帶寬。Flat-top窄帶濾波器是理想的激光雷達、拉曼光譜和其他需要使用精密激光發射濾波器或激光清理過濾器的應用。

661.5-1 OD5 Ultra Narrow Bandpass

Ultra-narrowband optical interference filter with a 661.5 nm center wavelength (CWL), a 1 nm full-width at half-maximum (FWHM), and wide-range out-of-band blocking from 350 nm to 1000 nm. This is a multi-cavity filter with transmission that is greater than 95% at 661.5 nm. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and mounted in a 50 mm (+0/-0.1 mm) diameter, 3.5 mm (± 0.1 mm) thick anodized aluminum ring. 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.

1650.96-0.8 OD4 Ultra Narrow Bandpass

Ultra Narrow filters bring new levels of performance to filters with very narrow bandwidth responses. Typically fully blocked to OD4 or OD6 and < 3 nm wide at FWHM, Alluxa Ultra Narrow Filters are uniquely steep and accurate. All Alluxa Ultra Narrow filters are fabricated with a proprietary durable, hard coating process. Even very narrow ( < 0.5 nm at FWHM ) Ultra Narrow filters typically have transmission values > 90%.
