Abstract
A laser system comprising a laser assembly for generating a light beam, and collimation assembly movable axially with respect to the laser assembly and being positioned in the optical path of the light beam. The collimation assembly comprises a collimation lens group comprising a first lens component positioned within a first lens mounting cell, a second lens component positioned within a second lens mounting cell and provided with a central portion for receiving and cooperating with the first cell to thereby adjust the axial spacing between the first and second lens components, means for radially adjusting the position of the second cell with respect to the first cell to thereby radially adjust the optical axis of the second lens component with respect to the optical axis of the first lens component, and means formed in the central and flange portions of the second cell for creating flexure therein.
