Abstract
Disclosed are apodizers and methods for redistributing the intensity of a light beam. Particularly, single component apodizers are disclosed. The single component apodizers include a single lens component that is capable of redistributing the intensity of a coherent light beam.
Claims18
A method of redistributing the intensity of a collimated beam of light comprising:
- projecting a collimated beam of light through a single component lens having two aspheric surfaces, wherein the single component lens produces a collimated beam of light with a flat-top intensity distribution.
A single component lens for redistributing the intensity of a collimated beam of light comprising:
- a first surface that refracts a collimated light beam entering the single component lens;
- and
- a second surface that recollimates the refracted light beam,
- wherein the light beam has a first intensity profile when entering the single component lens and a second intensity profile when exiting the single component lens.
