Abstract

A method and a device for producing an optical component having at least three monolithically arranged optical functional surfaces and an optical component are disclosed. The method includes calculating a continuous surface composite, which includes the first optical functional surface and the second optical functional surface, producing the continuous surface composite, which contains the first and second optical functional surfaces in a defined shape and a relative position to one another, on the first side of the optical component through machining by a machine tool, producing at least one reference surface arranged outside the optical functional surfaces on the optical component or on a mount and having a defined positional relation to the optical functional surfaces through machining by the machine tool and repositioning the optical component in such a way that the second side of the optical component is machined with the machine tool, wherein the at least one reference surface serves as a contact surface or mounting surface.
