FIELD: optics. SUBSTANCE: proposed microlens incorporates three components. First component includes n frontal single lenses, second component has two double-cemented lenses, first comprising negative and positive lenses and second is cemented of positive and negative lenses, third is made of double-cemented positive and negative lenses and of triple-cemented lens incorporating positive lens confined between negative lenses. Number of n frontal single positive lenses can be from 0 to 3. EFFECT: provision for achievement of plano-achromatic aberration correction in microlens with extended working distance. 1 cl, 1 dwg
