窄带滤光片

Narrow Bandpass Filters

Alluxa 高性能滤光片以先进的设计工艺和镀膜过程控制,使Alluxa滤光片具有行业内高的透过率,极高的截至深度和波长精确性,其中通过SIRRUS™离子束沉积硬镀膜技术,也使得Alluxa滤光片具有使用寿命长,高损伤阈值,以及极高的批次稳定性等特点,并已经广泛应用于生物荧光系统、拉曼系统、量子、雷达通讯等精密光学系统中。

Alluxa除了丰富的标准品,同时提供定制服务,并且定制成本在行业内有相当大的竞争力.

具有OD6阻断的超窄带滤光片,用于1064 nm Nd:YAG激光器。

凭借业界窄的带宽和高的透过率,Alluxa的薄膜超窄带带通滤光片将优化基于激光的系统的性能。

超窄滤光片非常适合用作激光线,激光清除或激光激发滤光片,适用于荧光显微镜,流式细胞仪和DNA测序等应用。它们对激光损伤也很有抵抗力,可确保它们长时间保持高水平的性能。

应用:LIDAR, 拉曼光谱, 及需要净化激光器的精密光学系统.

特点:

  • 透过率:可达99%
  • 窄带宽: 0.1nm
  • 截至深度: ~OD10
  • 波长范围: 250nm~6.2 µm可选
  • 中心波长精度:0.05nm
  • 透过波前差(RMS): 优0.01λ per inch @ 632.8 nm

精密控制用的Flat-topAlluxa

具有陡峭边缘,深度阻挡和方形光谱形状的平顶超窄带通滤波器。

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 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。 Contact us for custom sizing options。
