Detailed Product Description Penta Prism, Glass PrismThe deviation angle of 90 is thus independent of the orientation of the prism, making it especially important in applications in which the prism orientation can not be precisely controlled. Due to geometry that total internal reflection cannot...

Detailed Product Description Optical Prism -- Right Angle PrismA Right-Angle Prism is used as a mirror to deviate light through 90 degree, and also as a retroreflector to deflect light throgh 180 degree by total internal reflection.90-degree Deflection90 degree deflection occurs at the hyotenuse...
