A method for production of a substrate having a patterned optical coating on a curved surface is provided. The method includes applying a masking to a sub-area of the curved surface applying an optical coating using a vacuum deposition method, and removing the masking. A coated substrate, which can be produced in particular by the method described above, is also provided. The coated substrate includes a curved surface that is provided with at least one patterned optical coating. The at least one patterned optical coating is provided on at least one sub-area of the curved surface and is missing on at least one adjacent sub-area.

Coated substrate with a curved surface, and a method for production of a coated substrate such as this

A color filter () for illumination purposes, such as, for example, for stage illumination is proposed, which comprises a full-surface antireflection layer () and an additional, multilayered structured interference filter layer () arranged on it.

Color filter and method for its manufacture

The invention provides a process for producing at least one optical filter layer segment on a substrate. The process includes The deposition of the optical filter layer, at least at times, takes place at a temperature of over 150&#xb0; C., preferably in a range from over 150&#xb0; C. up to and including 400&#xb0; C.

Process for producing patterned optical filter layers on substrates

The invention provides a process for producing a high-precision reflector and its coating. A reflector is produced from a solid material using a material-removing process and is coated with a cold-light mirror layer.
