Abstract
The invention relates to an optical filter and a method for its production, and to a device for the examination of the spectral and spatial distribution of an electromagnetic radiation irradiated from an object. The invention is based on the task of providing an optical filter of the above described type that is inexpensive to produce, which can be used to detect a plurality of wavelengths, in which, however, tuning of the DBR mirrors by means of displacement is not necessary. Furthermore, a method for the production of such a filter is provided. According to a first aspect of the present invention this task is solved by a method for the production of an optical filter array having two DBR mirrors, and a cavity present between the same, comprising cavity sections having a plurality of different heights, each forming one Fabry Perot filter element, characterized by the following steps: applying a first DBR mirror onto a substrate, forming of a layer comprised of a cavity material on the DBR mirror, wherein this layer is equipped with a plurality of cavity sections forming the filter elements by means of utilizing a nanoimprint method, and applying the second DBR mirror on the cavity material having a structuring that is defined by the different heights of the cavity sections.
