An optical arrangement has a plurality of optical elements capable of transmitting a beam. A partial housing is provided which extends from a surface of an optical element in the direction of the beam emanating from the optical element, or of the beam incident on the optical element, and whose shape is adapted to the shape of the beam. The partial housing is surrounded at least partially by a measurement structure which is mechanically decoupled therefrom. The measurement structure has at least one sensor.
