ABSTRACT:
A reflecting microoptical system is formed of only two optical surfaces having a continuous configuration, and has a simple configuration suitable for glass molding. Different combinations of convex, planar and concave surfaces are disclosed for the two optical surfaces, to provide different advantageous properties. In preferred embodiments of the invention, at least one, and in some cases both, of the optical surfaces have an aspherical shape to correct for aberrations.
