Hybrid Mode Optical Monitoring – Benefiting from Monochromatic and Broadband Algorithms in the same Coating Process

 Broadband monitoring with high signal quality enables use of both broadband and monochromatic layer termination algorithms in the same process when depositing optical interference coatings. Case studies using a bandpass filter and an absorbing layer show how such a “hybrid” approach can lead to the most accurate layer termination.
