Zusammenfassung:According to embodiments of the present invention, an apparatus comprising a beam shaping element (lens) is provided. The apparatus comprises a substrate; a beam shaping element; and an elastic intermediate layer disposed between, and in contact with, the substrate and the beam shaping element, wherein the elastic intermediate layer has a Young's Modulus in a range of 2-600 MPa and a Poisson's ratio in a range of 0.2-0.5. Techniques for reducing thermal distortion of lens are described.
