Method, optical filter system, optical measurement device and use

Method for manufacturing an optical filter system, wherein the optical filter system comprises:

• i) a plurality of filters, each having a specific spectral sensitivity, and ii) a filter frame holding the plurality of filters in a predefined pattern;
• and
• wherein the method comprises, per said filter of a said specific spectral sensitivity, the steps of:
• applying a plurality of filter coatings on a substrate to obtain a coated substrate provided with a stack of filter coatings, which stack is designed for the specific spectral sensitivity of the respective filter,
• dividing the coated substrate into a plurality of substrate portions,
• examining the coated substrate to determine the good ones of the substrate portions, the good ones being the substrate portions where the coated substrate meets a predefined design requirement associated to the specific spectral sensitivity-of the respective filter,
• after having determined the good ones, dicing the coated substrate into the plurality of substrate portions, and
• picking a said good one of the substrate portions as the filter
• wherein the method further comprises a step of configuring the filters picked and the filter frame such that the filter frame holds the plurality of filters in the predefined pattern.
