COMPLEX ULTRACOMPACT OPTICS

摘要

The complex ultracompact optical system is comprised of a monolithic block (1) of optical material having two opposite aspherical surfaces, the primary mirror (5.2) and a convex or concave aspherical specular surface forming the secondary mirror (4.2) having a circular shape; the rays are refracted when entering the optical material and are then reflected in the primary mirror formed by the surfaces of the optical material having a generally converging shape, and , and in the secondary mirror formed by the surface of the optical material in a convergent or divergent shape, one or several times, and finally is refracted when coming out of the optical material. Application to the fabrication of magnifying lenses, eyepieces, microscopes, terrestrial finders such as telescopes and binoculars, photographic camersas and also to any instrument or apparatus wherein invisible radiation is used or generated. <IMAGE>
