Patent ID: 7387395

Claim:
An optical unit comprising an optical element deviating from a circular shape, for an optical imaging system, and a supporting part which is provided with reference surfaces for adjustment to said optical imaging system, said supporting part being connected to said optical element, and said reference surfaces being referred to a zero point relative to said optical element which forms a reference point with a zero point fixed in said optical imaging system during installation of said optical unit in the optical imaging system; wherein the reference surfaces are provided on said supporting part and comprise at least three coplanar reference surfaces which form a reference plane; a first locating edge, lying at an angle to the coplanar reference surfaces, of said supporting part; a second locating position by means of which translatory displacements along the first locating edge are avoided; wherein said supporting part is provided with an underpart on the side avert from said optical element; wherein a basic body with a plane surface is provided via which said basic body is connected to said supporting part, and wherein said basic body has a reflecting surface as the optical element; and wherein the supporting part, the reflecting surface and the underpart comprise individual parts, and wherein said individual parts of said optical unit are connected to one another by wringing.
