FIELD: optics, biology, medicine. SUBSTANCE: proposed achromatic high-speed objective lens is intended for completion of set of passing light microscopes of large series (biological, polarizing, luminescent and other types). It is composed of five components: first and second ones - positive components fabricated in the form of meniscus-like lenses facing image space with convexity, third and fourth ones - bonded components. Third component includes positive lens confined between two negative ones. Fourth component is composed of positive biconvex and negative lenses. Fifth component is manufactured in the form of single negative meniscus facing image - space with concavity. EFFECT: expanded application field. 1 dwg , 1 tbl
