特性
- 提供Ø1/2英寸、Ø1英寸，Ø2英寸和Ø75 mm 透镜，安装在SM螺纹外壳中
- 紫外级熔融石英
- 波长范围：185 nm - 2.1 μm（未镀膜）
- 焦距可选择20.0 - 1000.0 mm
这些紫外级熔融石英平凸透镜可选择Ø1/2英寸、Ø1英寸，Ø2英寸和Ø75 mm 尺寸安装在螺纹安装座中，波长范围是185 nm - 2.1 μm。紫外级熔融石英在深紫外波段具有很高的透过率，并且几乎不产生激光诱导荧光（测量波长193 nm），这使其特别适合应用于紫外到近红外波段。另外，与N-BK7相比，紫外级熔融石英具有更好的均匀性和更低的热膨胀系数。
平凸透镜具有正焦距，是应用最广泛的透镜元件。它们一般用来对准直的入射光进行聚焦；在这种情况下，为了最小化球差，准直光束应从透镜的曲面入射。当成像质量不重要时，平凸透镜也可以作为消色差双胶合透镜的替代品。
虽然平凸透镜和双凸透镜都可以对准直入射光进行会聚，但在选择时，如果想要获得低于0.2或者大于5的绝对放大率，通常倾向于选取平凸透镜。当需要的放大率介于0.2和5之间时，使用双凸透镜比较适合。
