精密控制用的Flat-top Alluxa窄带滤光片Ultra

Alluxa窄带滤光片（Flat-top）片具有极佳的截至陡度，深度截至和正方形的光谱形状

Flat-top,超窄的带通滤波器特别设计，在整个通带中有极陡的边缘和高透过率。这个正方形的光谱形状可以达到0.1 nm的带宽。Flat-top窄带滤波器是理想的激光雷达、拉曼光谱和其他需要使用精密激光发射滤波器或激光清理过滤器的应用。

661.5-1 OD5 Ultra Narrow Bandpass

Ultra-narrowband interference filter centered at 661.5 nm with a 1 nm FWHM and wide-range out-of-band OD5 blocking. Alluxa ultra-narrow bandpass filters have the narrowest bandwidths and highest transmission currently available. All Alluxa filters are hard-coated, 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%.
