Beamsplitters
are used to split or combine beam of light. Plates and cubes
are the most common types. The performance of beamsplitters
are mainly depended on the coating specifications. In selecting
beamsplitters, the forms, coating, transmission and damage
threshold should be considered.

Beamsplitter
plates can be used with high power laser. When using
beamsplitter plates, 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 plates. |

Compared
with beamsplitter plate, beamsplitter cube has the
following advantages:
- Identical
path lengths for both the reflected and the
transmitted beams
- The
transmitted beam is neither displaced nor deflected.
- Stable
and compact.
- Easy
operatio
- Easy
to Mount/Align

The
prisms can be used as polarizers, beamsplitters
or beam combiners. The output beam which are parallel
to input beam is called p-polarized beam while
the orthogonal output beam is defined as s-polarized
beam.

With
special designed multi layer dielectric coating,
the mirror reflect some wavelength and transmission
other wavelength at the same time.
It can be used to splitter or conbine different
wavelength.
It can be also used in SHG laser system as Harmanic
Separators. |
