PLANO-ACHROMATIC HIGH-SPEED MICROLENS OF BIG ENLARGEMENT

摘要

FIELD: optics. SUBSTANCE: plano-achromatic high-speed microlens of big enlargement is meant for completion of reflected light microscopes used in clear field in normal and polarized light. Microlens is composed of two groups of components. First group includes single meniscus, component cemented from negative and positive) lenses, component cemented from two biconcave lenses, biconcave lens placed between them, component cemented from positive and negative lenses. Second group includes single biconvex lens (dispersion factor of its material exceeds 70) and meniscus cemented from two meniscus-like lenses facing image space with concavity or from biconvex and biconcave lenses. EFFECT: expanded application field of high-speed microlens. 2 dwg
