Abstract

Described herein is a lens having at least one object-side and at least one image-side refractive surface. In order to determine a light intensity of an effective luminous flux propagating through the lens without the need for additional components for coupling light out, the lens includes a reflective surface arranged between the object-side and the image-side refractive surfaces and aligned obliquely to the optical axis.
