EQUIPMENT AND METHODS FOR MEASURING THE OPTICAL PROPERTIES OF OPTICAL SYSTEMS

Abstract

The device, due to the optical properties of the optical system (12; 112; 212), has an object (flood) that needs to be photographed, with structures (18) arranged in a plane and separated from each other, a two-dimensional image sensor (32) and an optical collecting unit (30) with focal length f. The image sensor (32) has a distance from the optical collecting unit (30) equal to 0.9 f < a < l,l f. The support (13) for the optical system (12; 112; 212) is arranged so that the optical system is placed in the purple beam line between the object (16) and the optical collecting unit (30). According to the invention, the image sensor (30) and the optical collecting unit (30) are designed in such a way that all structures (18) can be photographed by the optical system (12; 1 1 2; 212) and the optical collecting unit (30) onto the image sensor (32) simultaneously,
