道威棱镜
道威棱镜是一种像旋转器。通过道威棱镜观察图像时，图像呈现上下颠倒。而且旋转道威棱镜时，图像的旋转量为2倍。道威棱镜只能用在平行光。BETVLCTOR伟德国际体育可接受各种镀膜需求。此外，它的反射面必须非常干净，灰尘不可落到棱镜的表面上
The Dove Prism is also called Image Rotator. The prism rotates the image without changing the direction of the input beam, which is parallel to hypotenuse. Rotation of the prisms in relation to the subject causes double rotations of the image. Dove Prism should be used in the parallel beam. A-STAR also offers Dove prisms AR coated on the hypotenuse for use in beam-folding applications. As the S1 and S2 sides are used in a total internal reflection (TIR) manner, it is extremely important to keep these two surfaces clean.
