Home / Custom / Optical Components / Optical Prism / Penta Prism 
Penta prism is a very unique and precise prism that can be seen as a beam deflector. Its core ability is that no matter how you hold it or how you tilt it, as long as the light enters from the correct side, it can make the beam bend precisely by 90°, while ensuring that the direction of the image does not change.
