Paper Abstract

An optical system for laser eye protection application is presented. The optical device includes a first lens having a positive power of magnification a second lens having a negative power of magnification and a flat interference based reflector(s) between the two lenses. Incoming light rays are redirected by the lenses so that they pass through the interference filter at normal incidence. 1.
