Beamsplitter
Plate |
| |
| The beamsplitter plates
are used for most laser applications. The can be used with high
power laser. When they are used, it is important to bear in mind
that the two partial beams travel different optical paths. And the
optical paths depend on the incident angle and the thickness of
the plates.
