| Here's a 40mm wide by 70mm tall penta prism that has been polished on some of the 5 sides, but not all. The others are ground and ready to be polished. If you can polish two or three sides, you've got yourself a prism similar to the one that Edmund sells for $161.70. A penta prism is a 5 sided prism that reflects light rays thru a 90 degree angle by two reflections and does not invert or revert the image. |
