OPTICAL FILTER, IR SENSOR, AND LIGHT EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18275899 titled 'OPTICAL FILTER, IR SENSOR, AND LIGHT EMITTING DEVICE
Simplified Explanation
The patent application describes an optical filter that includes a matrix with an inorganic substance and a wavelength selective absorption material dispersed in the matrix. The filter absorbs optical components within a specific wavelength band of 0.8 to 20 μm. The filter has a high temperature resistance and a high apparent density relative to the true density of the matrix.
- Matrix with inorganic substance and wavelength selective absorption material
- Absorbs optical components in specific wavelength band
- High temperature resistance

Original Abstract Submitted
Provided is an optical filter including: a matrix including an inorganic substance having a water solubility of 0.4 g/100 g-HO or less; and a wavelength selective absorption material dispersed in the matrix. The optical filter absorbs an optical component having a wavelength of any band in a target wavelength band of 0.8 to 20 μm. A temperature at which a mass reduction rate of the wavelength selective absorption material is 10% by mass when heated in air from 100° C. at a rate of 10° C./min is 900° C. or less. An apparent density of the optical filter relative to a true density of the matrix is 70% or more. In the target wavelength band, a wavelength bandwidth where a linear transmittance per 1 mm thickness of the optical filter is 30% or more is 50 nm or more.
