Beam Expander |
| |
|
 |
A
beam expander is any optical system designed to
increase the diameter of a laser beam. In most
cases, the term is taken to mean a telescope
designed to take a small-diameter collimated
beam input beam and produce a larger diameter
collimated output beam, thus reducing the
divergence of the beam. The beam expander
consists of a negative input lens and a positive
objective. The expansion factor is the ratio of
the focal length of the two lenses. |

Applications
|
|
|
-
Precision
laser machining: capable to provide a high power
density focal spot.
-
Laser
range finder: capable to provide a highly
collimated beam.
-
Combining
with a spatial filter, able to modify laser
power distribution.

Note: Can be transferred to
optical components such as
adjustment brackets, coaxial
systems, etc. with Ø2"
optical wall holes or SM2
threaded holes. The clamped
parts are mounted by means
of a lateral M4 captive head
set screw, which prevents
the clamped parts from
turning and sliding and
ensures that the centre of
the clamped parts is aligned
with the optical axis. the
M4 captive head set screw
can be adjusted and locked
with a 2.0 mm hexagonal
spanner. |

Note:
The locking screw allows the
mounting bracket to be
flexibly deformed to lock
the mount in place and does
not cause any damage to the
sleeve due to the length of
the screw. The bottom of the
mount has M4 threaded
mounting holes and can be
supported by a Ø12.7 mm
stainless steel optical rod
or other connection. |
