STUDY OF BASIC TWO-LENS COMPONENTS OF HIGH-APPERTURE OBJECTIVES FOR MODERN IMAGE INTENSIFIERS
Annotation
High resolution of modern image intensifiers is afforded by high-quality correction of residual aberrations in the lenses. For basic two-element components of the lenses made of Russian optical glass, calculations of relative values of partial and secondary dispersions in the range from 0,6 to 0,9 μm are performed. The set of basic two-element components with relative aperture of 1: 3—1 : 2,5, achromatized for the spectral interval, may serve as a basis for calculation of high-aperture lenses designed for modern image intensifier tube of II and III generations.
