Optical mount with UV adhesive and protective layer

An assembly, comprising:

• 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 said holder by said adhesive, in which said 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 said UV wavelength region transmitted by said transparent optical component, and is transparent in said given long wavelength region to harden said adhesive by UV light irradiation that passes through said transparent optical component and said layer.

A process for producing a transparent optical component attached to a mount by means of UV-hardenable adhesive, comprising:

• selecting a thin layer to transmit light in a given spectral region suitable for hardening said adhesive and to a high degree obstruct transmission of UV light in a predetermined spectral region by at least absorption or reflection, within a spectral region transmitted by said optical component, and
• covering said optical component with said thin layer in a region of said adhesive by thin film technology.
