Abstract
The article presents a new design of the sensor for measuring dust, which is based on the effect of absorption of optical radiation passing through the dust layer. Fundamentally new is the use of a powerful low-cost LED, the spectral part of the radiation range required for measurement of which is formed by the structure of auxiliary reflective optical interference filters. A technique based on the introduced stability criterion of the synthesized interference coating is developed, which makes it possible to study the transformation of the spectra with real errors in the film thicknesses.
