Abstract

PURPOSE:To measure optical characteristics of an optical system to be examined accurately by spliting the luminous flux past said system to two optical paths, passing these limiting masks disposed respectively with plural parallel linear patterns in mutually varying arrangement directions, and detecting the two spots of projected images. CONSTITUTION:The luminous flux from a light source 2a is reflected by a dichroic prism 3, and the luminous flux from a light source 2b transmits through said prism. Both these fluxes are made incident to a relay lens 4 and are focused at a pinhole 5. This luminous flux is made incident to a lens 8 to be examined through a collimator lens 6 and a reflection mirror 7, and the luminous flux out therefrom is made incident to a dichroic prism 11 via a reflecting mirror 9 and a relay lens 10. The transmitted luminous flux goes through a reflecting mirror 12 and a luminous flux limiting mask 13b and the reflected luminous flux goes through a reflecting mirror 17, and a luminous flux limiting mask 13a, by which these are respectively selected of the necessary information components of the optical characteristics of the lens 8, after which these fluxes are made incident to a half mirror 14, where they are partly reflected by a semitransparent film 14a and are made incident to a line sensor 16 and the other part transmit therethrough and are made incident to a line sensor 15, whereby these are detected.
