FIELD: optics. SUBSTANCE: microlens includes three groups of components. First group comprises frontal lens bonded from plano-convex and meniscus-like lenses and three positive single lenses. Second group includes two bonded positive components, first component being cemented together from negative lens contained between two positive lenses and second component being made up of biconvex lens and negative meniscus. Third group of components has two lenses cemented together, first one comprising positive and negative lenses and second one bonded from two negative lenses between which positive lens is placed. EFFECT: enlarged numerical aperture and lens speed with improvement of correction of polychromatic aberrations. 1 dwg
