 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. |
 Features Applications |
- Low power loss
- Good output collimation
- Able to withstand laser power of more than 1000 W
- Adjustable divergence angle of 18 to 32 mrad with the variable beam expanders
|
- 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.
