Abstract: An assembly includes a holder made of material selected from metal and ceramic/glass ceramic, a transparent optical component that is transparent in the ultraviolet (UV) wavelength region of light, which has functional faces serving for transmission, and adhesive that is hardenable by UV light of a given long wavelength region, a layer applied by thin film technology and fixed to the holder by the adhesive. The layer is provided only outside said functional faces and to a high degree at least reflects or absorbs radiated light in a predetermined UV wavelength region within the UV wavelength region transmitted by the transparent optical component, and is transparent in the given long wavelength region to harden the adhesive by UV light irradiation that passes through the transparent optical component and the layer.

Abstract: An assembly includes a holder and a transparent component that transmits in the ultraviolet spectral region and is adhered by means of an adhesive. The adhesive is hardenable by UV light with a given spectral distribution. A layer is applied by thin film technology on the transparent component in the region of the adhesive and transmits UV light of the spectral region suitable for hardening the adhesive and to a high degree reflects and/or absorbs UV light within a useful spectral region within the spectral region transmitted by the transparent component.
