FIELD: physics, optics. ^ SUBSTANCE: ocular comprises two components, the first of which along with direction of rays is two-lens and glued of concavo-concave and convexo-convex lenses, the second component is a convexo-convex lens. In ocular between structural parametres the following ratios are obtained: 1.64 < n1 < 1.78; 1.59 < n2 = n3 < 1.62; |R4| < |R5|, |R2| = |R3| = |R4|, where: n1, n2, n3 are indices of refraction of material in the first, second and third lenses for line e; R2, R3, R4, R5 are radiuses of the second, third, fourth ad fifth optic surfaces. ^ EFFECT: increased angular field in images space and removal of exit pupil with high quality of image and level of manufacturability. ^ 1 dwg |
