The invention relates to a narrow-band optical interference filter for a wavelength (μ0) comprising a plurality of dielectric layers, whereby said dielectric layers alternately have a high (nH) and a low refractive index (nL) and a first number of dielectric layers has an optical layer thickness of μ/4 or μ/2 or an integral multiple thereof. The invention is characterized in that a second number of layers in the layer system has an optical layer thickness differing from μ/4 and μ/2 resulting in a minimized overall layer.

The invention relates to a method and device for the simultaneous coating and moulding of a body (11) comprising the following steps: two mould halves (1.1, 1.2) of a moulding tool (1) for moulding a moulded body are brought together and mounted on the unit, an injection material is introduced into the mould halves (1.1, 1.2), so as to produce a moulded body (11), the moulded body (11) is evacuated, a gas is introduced into the moulded body (11), the plasma in the moulded body (11) is ignited, such that a coating is deposited on the inner side of the moulded body (11). After the completion of the coating the mould halves (1.1, 1.2) are separated, whereupon the moulded body drops out.

The invention concerns a plasma CVD system (in particular a plasma pulse CVD system) with an array of microwave plasma electrodes (2a, b, c, d). According to the invention, in order to improve the homogeneity of the layer, interference is prevented by controlling adjacent plasma electrodes (2a, 2b; 2b, 2c; 2c, 2d) in a chronologically offset manner. To that end, micropulses (A, B) are provided within the macropulses of the plasma pulse CVD process. Additionally, the uniformity of the layer deposition at the interfaces between adjacent modules can be optimized by radio-frequency excitation by means of suitable electrodes (6, 62a-c), magnetic fields or the configuration of the gas inlets (5). The surface coated in an operating cycle can thus be scaled as required.

The invention provides that for each surface of a substrate (2) to be coated, a plasma is injected into a coating reactor (1) used for carrying out microwave PCVD methods, and the surface to be coated is perpendicularly orientated with regard to the direction of spreading of the corresponding plasma. Dielectric compensating elements (4a, b) are introduced into the vicinity of the microwave injection points (3) and correct for non-homogeneities resulting in the distribution of plasma thicknesses by altering the microwave field distribution.

The invention relates to an optical substrate on which at least one layer is to be arranged in such a way that the propagation of light is influenced. The aim of the invention is to reduce the production time for one such substrate and to preferably significantly reduce the surface strains thereof. To this end, the inventive substrate is produced by means of an application method which is characterised in that at least one of the layers applied comprises halogen atoms or a halogen compound.
