Abstract
An opto-mechanical deflector system for an imaging system comprises at least one scanning mirror struck by a collimated light beam focused onto a flat image plane by a first plano-convex lens, a concave mirror and an aplanatic lens system containing a plano-concave lens and a second plano-convex lens between said scanning mirror and said first plano-convex lens, the refractive indices of said first plano-convex lens and said plano-concave lens being substantially indentical and the refractive index of said second plano-convex lens being substantially less than that of said plano-concave lens.
