Abstract

本实用新型公开了一种测量仪器用外反射镜,它包括A反射面、B反射面、反射体,所述反射体后端设有两个错位凹槽,所述凹槽里面填充不透光材料,本实用新型在反射面后端加工两个错位凹槽,在槽中填充不透光材料,实现了零透射率,减少了制造成本。

Description

测量仪器用外反射镜
技术领域
本实用新型涉及一种测量仪器,特别涉及一种用于光路复杂的零透射外反射镜。
背景技术
一个光路中的外反射镜其反射率不可能达到100%,当该反射镜同时处于另一光路中,其透射的部分光就会对另一光路的性能产生影响。减小透射率的一般技术手段是提高反射膜反射率或使用不透光的反射体,都会造成制造成本的上升。
发明内容
本实用新型的发明目的是为了克服上述背景技术的缺点,提供一种结构简单易于实现零透过率的测量仪器用外反射镜。
本实用新型的发明目的是通过如下技术方案实现的:一种测量仪器用外反射镜,它包括A反射面、B反射面、反射体,所述反射体后端设有两个错位凹槽,所述凹槽里面填充不透光材料。
所述B反射面可以与A反射面成任意角度。
本实用新型的有益效果是:本实用新型在反射面后端加工两个错位槽,在凹槽中填充不透光材料,实现了零透射率,减少了制造成本。
附图说明
图1为本实用新型的结构示意图;
图2为本实用新型实现零投光率的光路示意图;
其中:1、A反射面,2、反射体,3、凹槽,4、B反射面。
具体实施方式
本实施例为一种测量仪器用外反射镜,它包括A反射面1、B反射面4、反射体2。
如图1所示反射体2后端设有两个错位凹槽3,凹槽3里面填充不透光材料。
如图2所示光源经过A反射面后,透射的光受到了两道错位槽的阻拦,形成了零透射率的效果。

Claims (2)

1.一种测量仪器用外反射镜,其特征是它包括A反射面、B反射面、反射体,所述反射体后端设有两个错位凹槽,所述凹槽里面填充不透光材料。
2.根据权利要求1所述的测量仪器用外反射镜,其特征是所述B反射面可以与A反射面成任意角度。
