Abstract

The present invention provides both continuously and discretely (54) variable spot size illuminators (10, 38, 42, 46) to provide a light spot on a treatment plane (28, 66) whose size can be adjusted while ensuring that the light fluence and the working focal distance remain substantially constant at all spot sizes. In a continuous illuminator, a focusing lens system (16, 18) is employed to form an image of a light source on an intermediate plane (20), and a variable aperture (22) is utilized to select a portion of the intermediate image. An objective lens system (26, 30, 64) then images the selected portion of the intermediate image onto a treatment plane (28, 66). A discrete illuminator employs a plurality of light shaping diffusers (56) to select the shape and/or size of an image formed on a treatment plane (66) from among a number of choices.
