For penta prism, the deviation angle of 90? is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled. We can supply high dimension and angle control penta prism. The coating or painting is designed by customer according to it is detailed application.
