FIELD: optics. SUBSTANCE: given microobjective is related to passing light microscopes meant for investigation of biological objects. It includes five components. First and second components are positive components in the form of single meniscuses with concave surfaces facing image space. Third component is bonded from negative and positive lenses. Fourth component is also bonded and fifth component is manufactured in the form of negative meniscus facing image space with concavity. Fifth component is made from optical material having refractive index not more than 1.65 and dispersion coefficient less than 30.0. EFFECT: enhanced operational efficiency. 1 dwg , 1 tbl
