AFOCAL GLASSES, MAGNIFYING SPECTACLES, TELESCOPE CUPOLAS, CUPOLA SEGMENTS OR THE LIKE AND COMBINATIONS WITH OPTICAL SYSTEMS KNOWN AS WEAK BINOCULAR WITH LARGE FIELD OF VISION, GOOD IMAGE DEFINITION AND HIGH LIGHT EFFICIENCY

摘要

afocal lenses with spherical-concave-convex boundary surfaces and with the same center of curvature as small telescope with a large field of view and as additional elements for optical devices. Description of principles plano lens manufacturing according to formulas Snell and Reiner and exposure lenses practical application possibilities afocal telescopes in domes, telescopes and in combinations with periscopes, cameras, microscopes, light guides and documentation systems.
