Penta Prism
For penta
prism,the deviation angle of 90¡ã 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. OP-Unite can supply high dimensionand angle
contorl penta prism. The coating or painting is designed bu customer
according to it is detailed application.
It is widely used in projection optical systems,
imaging optical systems, optical measurement and display systems. |

The general tolerance specifications above provide a
guideline regarding manufacturing capabilities for optics ranging in
size from 5-50.8mm. The manufacturing limits are not absolute;
tighter tolerances may be possible. Part specific tolerances may
vary depending on component size, shape, and/or
material. |
