Abstract:
1. An apparatus for tilting an optical element, the apparatus comprising: a frame; a carrier fastened on the frame via at least one articulated connection; an optical element supported on the carrier and having first and second optical faces, the first and second optical faces being arranged together on the carrier and being fixed at a fixed angle relative to one another, wherein the carrier is arranged to pivot about three tilting axes, the first optical face is capable of tilting about a first tilting axis that extends normal to the plane of the second optical face, the second optical face is capable of tilting about a second tilting axis that extends normal to the plane of the first optical face, and a third tilting axis being located parallel to the line of intersection between the two planes of the first and second optical faces; and wherein said first tilting axis is located at the point at which a first optical axis passes through the plane of said first optical face, and in that said second tilting axis is located at the point at which a second optical axis passes through the plane of the second optical face.
