The inventive apochromatic objective lens relates to optical instrumentation and can be used in astronomic telescopes for visualising and photographing. Said apochromatic objective lens consists of three components, the first of which is embodied in the form of a double-convex lens, the second component consists of three lenses, i.e. a double-convex lens, a double-concave lens and a positive meniscus and the third component consisting of double-convex and double concave lenses. All the lenses are made of two types of ordinary optical glass, the dispersion factors of which meet the following requirement: 1.451<1.55, 1.652<1.75, 50< &gammad;1<60, 30<&gammad;2<40.
