Abstract
A laser imaging system comprising: a laser for producing a laser beam; and a moving mirror for repetitively reflecting the laser beam over a range of incidence angles to scan the laser beam in a line scan direction; wherein the mirror includes a metallic reflective layer and a multilayer transparent coating on the metallic reflective layer, the multilayer transparent coating including alternating layers of first and second dielectric materials, the thickness of the layers and the composition of the first and second dielectric materials being chosen such that the mirror (a) achieves greater than 90% reflectance over the range of incidence angles, and (b) exhibits minimum reflectance variations over the range of incidence angles.
