A method of designing multi-cavity infrared narrowband filters for bandwidth between 10% and 20% is presented: The method is based on a Tschebysheff prototype. The theoretical indices from these are simulated by Herpin equivalent layers, the outer layers may be also simulated by Herrmann's asymmetrical tri-layer. The new algorithm of filter design can easily be implemented in any microcomputer.
