Dispersing Prism
| Dispersing Prism (also named Equilateral Prism) is a normally used as
dispersing prisms. For all standard Schott BK7 prism high index, Schott SF2 and F2
prism are offered to increse the dispersive power. |

Note: The general tolerance specifications above provide
a guideline regarding manufacturing capabilities for optics ranging
in size from 3-76.2mm. The manufacturing limits are not absolute;
tighter tolerances may be possible. Part specific tolerances may
vary depending on component size, shape, and/or material. |
