摘要:
In order to more simply and cost-effectively produce optical components or systems having at least two optical elements, preferably at least one diffractive element and a further refractive and/or diffractive element, and preferably to improve the optical properties of such components and systems, the invention relates to an optical component having a diffractive and/or refractive element which comprises a photosensitive glass and/or a photosensitive glass ceramic, which have structures influencing the light propagation at least in a part of their volume. The invention also relates to a method for producing such an optical component.
摘要:
In the method for microstructuring flat glass substrates a substrate surface of a glass substrate is coated with at least one structured mask layer and subsequently exposed to a chemically reactive ion etching process (RIE) with at least one chemical etching gas. In order to provide the same or a higher quality etching and etching rate even for economical types of glass the chemical etching gas is mixed with at least one noble gas, so that the proportion of sputtering etching in the ion etching process is significantly increased.
