Problems solved by technology

However, in the case of the application described in EP 0 950 693 A1, a disadvantage is that the possibilities for adjusting the spectral properties are limited, since for example only a limited number of layers can be deposited during the production of these pigments

Embodiment Construction

[0222] example

[0223] In the Satisloh 1200-DLF coating unit, an extensive substrate material in the form of a plastic substrate coated with polysiloxane-based hardcoat material MP-1154D (SDC TECHNOLOGIES, INC.) was used as A carrier base material is provided.

[0224] The plastic base material was an uncoated ophthalmic lens made of CR39 polymer and had a circular diameter of 6.5 cm, and a median thickness of 1.5 mm. First, primer PR-1156 (SDC TECHNOLOGIES, INC.) was applied to the plastic base material by dip coating in a layer thickness of 750 nm. Dry in a ULE 600 upright oven at 70 °C for 5 min at D-91126 Memmert GmbH + Co. KG, Schwabach, Germany. The polysiloxane-based hardcoat material MP-1154D was subsequently applied by dip coating with a layer thickness of 2500 nm. It was then dried and cured for 120 minutes at a temperature of 110°C in a ULE 600 upright oven of the company D-91126 Memmert GmbH + Co. KG in Schwabach, Germany.

Abstract

The invention relates to an interference layer system comprising a plurality of optically transparent layers. The interference layer system does not have a carrier substrate, and the optically transparent layers are arranged so as to lie flatly one on top of the other. The optically transparent layers are selected from the group consisting of dielectrics, metals, and combinations thereof. At least one first optically transparent layer has a refractive index n1, and at least one second optically transparent layer has a refractive index n2, and the first refractive index n1 and the second refractive index n2 differs by at least 0.1. The invention additionally relates to the production and use of the interference layer system.

Description

technical field [0001] The invention relates to an interference layer system comprising a plurality of optically transparent layers. The invention further relates to a method for producing such an interference layer system and to the use of such an interference layer system. Background technique [0002] Optical interference layer systems have been known for a long time and are used for a variety of different purposes. Common to all optical interference layer systems is the thickness of the employed layers on the order of the wavelength of light. For example, the layer thicknesses differ depending on whether the optical interference layer system is designed for short wavelengths, such as the UV spectral range, or for longer wavelengths, such as the infrared (IR) spectral range. Optical interference layer systems consist of layer stacks with different refractive indices. Depending on the objective, the layer stack is characterized by a different number of individual layers...
