屋脊棱镜
产品描述：
屋顶棱镜是一种反射式光学棱镜，它两束交叉的光相互平行。它包含两个面以90°角相交的截面。这两个90°的面类似于建筑物的屋顶，因此该类型棱镜也因此得名。来自两个90°面的反射将返回一个图像，该图像在两个面相交的轴上横向翻转。
在某些情况下，通过棱镜时，图像会从右向左和从上到下偏转。棱镜的斜边利用全内反射（TIR）通过棱镜反射图像。偏振态在反射过程中可能发生旋转。
作为一家经验丰富的供应商，光骅达光电公司为客户提供多种屋脊棱镜材质选择，如各种光学玻璃（如N-BK7）、熔融石英、硅、ZnSe、ZnS、CaF2、MgF2等等。

Roof  Prism
A roof prism is a reflective optical prism to make two cross beams be parallel with each other. It contains a section where two faces meet at a 90° angle. These two 90° faces resemble the roof of a building, giving this prism type its name. Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet.
As a rich experienced supplier, substrate material in Photonchina can be chosen from all optical glasses (N-BK7, for instance), Fused Silica, Si, ZnSe, ZnS, CaF2, MgF2 etc.
