WebMultilayer thin-film structures have been used to model and analyze the performance of broad-band-pass interference optical filters in visible spectrum. Starting from nine-layer configuration comprising quarter-wave layers, the number of layers is increased to make the pass band smooth with steep slopes and square band-pass characteristics. The layer … WebThin-film optical filters are made by depositing alternating layers of materials onto a substrate, such as optical-grade glass. Depending on the wavelength and filter design, light can be reflected off of the optical filter, transmitted through it, or absorbed by it. There are 5 basic categories: bandpass, notch, shortpass, longpass, and dichroic.
