Title:
ULTRA-THIN THIN-FILM OPTICAL INTERFERENCE FILTER
Document Type and Number:
Japanese Patent JP2023178283
Kind Code:
A
Abstract:
To provide a thin-film interference filter.SOLUTION: A thin-film interference filter has a thin-film interference multi-layer stack composed of individual thin-film filters arranged in groups to form a plurality of repeat unit blocks. The thin-film interference filter is flexible enough to be bendable to a radius of curvature of 250 mm or even less without permanently damaging the thin-film interference filter. The thin-film interference filter may have a second thin-film interference multi-layer stack composed of individual thin-film layers arranged in repeat unit blocks, and such thin-film layers may have different optical transmission spectra from each other. At least one interlayer between the first thin-film interference multi-layer stack and the second thin-film interference multi-layer stack may block a range of wavelengths of infrared, visible, or ultraviolet light. A defect layer of a different optical thickness from neighboring thin-film layers forms the repeat unit blocks, thereby creating a Fabry Perot cavity resonator.SELECTED DRAWING: Figure 1
