Homogenizer product line flexibly converts any collimated input laser beam into a well-defined beam with homogenized intensity and desired shape.

Homogenizer product line flexibly converts any collimated input laser beam into a well-defined beam with homogenized intensity and desired shape.

Using our Beam Homogenizer product, you can convert any collimated input beam profile into a well-defined beam with homogenized intensity. Any desired shape, for any wavelength can be achieved.

A Beam Homogenizer is very useful in many applications requiring a well-defined beam shape with a randomly-diffused intensity profile.

The output of the Beam Homogenizers will depend on the input beam profile:

A multi-mode laser beam actually has an advantage when used with beam homogenizer, as their degraded coherence will reduce the visibility of speckles and therefore create a more uniform intensity profile than with single mode laser input.

Remark:

  • The above specifications are with regards to the collimated laser beam. If the beam is not collimated, the specifications may change a little.
  • The above specifications are with regards to the un-coated elements. If coating, the transmission will be higher in about 8%.
  • A focusing lens may be required for smaller beam size.
