ACHROMATIC MICROOBJECTIVE OF AVERAGE MAGNIFICATION Russian patent published in 2003 - IPC

FIELD: microscopy, microobjectives used to study superthin microscopic structures in natural light and in luminescence light. SUBSTANCE: achromatic microobjective has three components arranged in series along optical axis. First component presents singular positive lens coming in the form of meniscus facing object with concavity. Second component is cemented from three lenses, two biconvex and one biconcave lenses. Third component is double lens component manufactured in the form of singular meniscus facing object with convexity and biconvex lens.
