发明名称 OBJECTIVE WITH VARIABLE FOCAL DISTANCE
摘要 FIELD: engineering of devices using several spectral ranges. ^ SUBSTANCE: objective has four optically connected components, first, second and third components contain three lenses each, and fourth one - five lenses, while second and third components are made with possible movement along optical axis. In objective, relations of optical strengths of lenses to optical strength of first components are, respectively, 0.6-0.83, -(0.95-1.1), 1.32-1.45, -(3.2-3.4),-(2.3-2.5), 2.3-2.5, 1.29-1.39,-(1.67-1.77), 2.35-2.5),-(3.9-4.3), 3.0-3.3, 2.1-2.3, 2.1-2.4, -(3.0-3.4), while materials of lenses have refraction coefficients, respectively, 1.55-1.65, 1.75-1.94, 1.54-1.66, 1.64-1.76, 1.47-1.57, 1.75-1.94, 1.43-1.57, 1.61-1.71, 1.43-1.53, 1.58-1.68, 1.54-1.66, 1.54-1.66, 1.54-1.66, 1.64-1.81, and dispersion coefficients, respectively, 45-55, 20-35, 55-72, 50-62, 54-71, 20-35, 71-85, 35-45, 75-95, 37-47, 55-72, 55-72, 55-72, 23-34. ^ EFFECT: quality image within spectral range from 0,45 to 0,9 micrometers. ^ 4 dwg
