Abstract: A method for production of window elements which can be soldered into a housing in a hermetically tight manner with optical coating and free-form window elements are disclosed. After application of optical coatings, a protective layer is applied to the optical coating, the two layer systems are selectively removed by means of a machining beam of high-energy radiation for the purpose of ablation of a desired optically active free-form surface for window elements with any geometric shape through a localized machining beam in edge regions of the optically active free-form surface such that the protective layer remains on the optical coating as lift-off mask which is lifted off after applying a metallization for a solder layer by an etching process that acts selectively only on the protective layer but not on the optical coating, and the metallization remains only on the peripheral edge regions circumscribing the free-form surfaces.

Abstract: A multispectral optical IR component with a hybrid coating DLC coating and an antireflection coating. The DLC coating has at least an outer layer with a first modulus of elasticity and an inner layer with a second modulus of elasticity which are arranged one above the other on the antireflection coating. The value of the first modulus of elasticity is greater than the value of the second modulus of elasticity. There is a transmissivity to IR radiation of at least 80% over a first determined wavelength range and over a second determined wavelength range. The first determined wavelength range lies in the range of mid-wavelength IR radiation, and the second determined wavelength range lies in the range of long-wavelength IR radiation.

Abstract: A method for designing an optical component for the IR range in which its desired technical characteristics are determined, and the optical component is simulated. The simulated optical component has a layer sequence of layers which are stacked one upon the other and have at least one low-index layer whose refractive index lies in a range from 1.35 to 1.7 and a high-index layer whose refractive index lies in a range from 3 to 5. Subsequently, a modified simulated optical component is generated in that at least one low-index layer of the simulated optical component is divided into at least two partial layers and a mid-index layer is inserted between at least two of the partial layers. The layer thicknesses of the modified simulated optical component are adapted by means of a further simulation such that the modified simulated optical component has the desired technical characteristics.

Abstract: In a method for the production of window elements which can be soldered into a housing in a hermetically tight manner and of a window element sealing a housing, the object of the invention is to achieve an improved hermetic sealing between window and housing through increased adherence and homogeneity in the metal coating and to prevent penetration of scattered light and unwanted radiation. Optically transparent, flat substrate material whose size is sufficient for a plurality of window elements is provided on at least one surface with an optical coating from which frame-like portions on a coated surface which enclose optically active surfaces of the window elements are subsequently removed, whereupon a metal coating that is used for producing a solder connection to the housing is applied to the generated portions having no coating, and the window elements are separated from the substrate material.
