FIELD: optics. SUBSTANCE: invention can be used to design objective lenses of microscopes with plan-apochromatic correction of aberrations in absence of inherent fog exposures for making up sets of metallographic and polarization microscopes. Given microobjective has first positive component produced in the form of single lens, second negative component having form of positive and negative lenses glued together, third negative component comprising negative and positive lenses cemented together, fourth positive component coming in the form of positive lens confined between two negative lenses glued together. EFFECT: provision for plan-achromatic correction with increase of numerical aperture, reduced fog exposure. 1 dwg
