产品详细描述
参数
YAG激光用聚光透镜是用于YAG激光基波的空气隙双合或三合透镜。在1064nm波长，以焦点光斑的尺寸小于或等于衍射极限为目标，对球差和彗差进行了优化。
- YAG激光用聚光透镜是用于YAG激光基波的空气隙双合或三合透镜。透镜分别由低分散的冕牌玻璃和高分散的火石玻璃制成。
- 在1064nm波长，以焦点光斑的尺寸小于或等于衍射极限为目标，对球差和彗差进行了优化此透镜校正了色差，所以指示用的氦氖激光或可见光带域的视频用观测光，和YAG 激光有相同的焦点位置。各透镜都镀了YAG（1064 nm）和 氦氖激光（633 nm）用耐激光防反射多层膜。
- 我们提供光学保护窗。此窗安装在透镜的聚光侧， 防止透镜损伤。

注意：
- 对于某一有效光束直径(d)，其汇聚后的光斑或光腰尺寸(W)和波长(λ)成正比，与开口数(N.A.)成反比。
- W = (2λ) / πN.A.
- 例如，假设有一束YAG高斯光束；λ=1.064 μm和d= 25 mm，选用YDL-30-80PY1聚焦，焦距f=80 nm，有效通光孔径 De=25 mm：
- W = (2 x 1.064) / (3.14 x (sin (tan-1 (25/2) / 80)))
- = (2 x 1.064) / (3.14 x 0.154)
- = (ø) 4.39 μm
- 检查光路和调整光轴时，请一定戴好激光防护镜。
- 另售的保护窗玻璃没镀防反射膜。
