Abstract
Изобретение относитс к испытанию оптической аппаратуры и может быть использовано дл бесконтактного контрол качества дво ковыпуклых линз, содержащих асферические поверхности. Цель изобретени - расширение диапазона параметров контролируемых линз. Компенсатор состоит из двух линз. Первой по ходу лучей устанавливаетс дво ковогнута линза 1, показатель преломлени которой больше, чем у второй положительной менисковой линзы 2, обращенной вогнутой поверхностью к первой линзе. Качество контролируемой линзы может определ тьс по диаметру кружка рассе ни , создаваемого системой, состо щей из компенсатора и контролируемой линзы. 2 ил.The invention relates to the testing of optical equipment and can be used for contactless quality control of two-convex lenses containing aspherical surfaces. The purpose of the invention is to expand the range of parameters of controlled lenses. The compensator consists of two lenses. A lens 1 is installed first along the rays, the refractive index of which is greater than that of the second positive meniscus lens 2, the concave surface facing the first lens. The quality of the monitored lens can be determined by the diameter of the scattering circle created by the system consisting of a compensator and a monitored lens. 2 Il.
