Claim 14:
15. An optical component, comprising a number N of individual parts, which are wrung together at at least N−1 planar joining surfaces, wherein
a cavity is present in a cross section of the optical component, said cavity being arranged in the interior of the optical component and being surrounded by the N individual parts, wherein
a first individual part ET1 has at least one first coating surface with a first coating applied thereon and the first coating surface has at least one first planar partial region,
the first individual part has at least one first joining surface FF1 from the set of the N−1 joining surfaces,
the first coating on the first planar partial region is set back by a parallel offset Δt in relation to the first joining surface FF1,
the parallel offset Δt is less than 200 nm,
the first coating is arranged in the interior of the optical component, and
wherein the optical component is provided for at least one design wavelength and/or a design wavelength range, and the parallel offset Δt is less than the design wavelength and/or the minimum value of the design wavelength range.
