OPTICAL FILTER, METHOD FOR MANUFACTURING SAME, AND OPTICAL MODULE

An optical filter (10) comprises a matrix (12) and fine particles (14) dispersed in the matrix (12), wherein the fine particles (14) have a parameter Ds of 8.0 to 30 inclusive, Ds being determined by a USAXS pattern and given by Ds = λ/(B·cosθ·Ra), where λ is the X-ray wavelength, θ is one half the...

Summary:An optical filter (10) comprises a matrix (12) and fine particles (14) dispersed in the matrix (12), wherein the fine particles (14) have a parameter Ds of 8.0 to 30 inclusive, Ds being determined by a USAXS pattern and given by Ds = λ/(B·cosθ·Ra), where λ is the X-ray wavelength, θ is one half the scattering angle 20(rad) providing a scattering intensity peak, B is the half width (FWHM, rad) of the peak, and Ra is the average particle size of the fine particles (14).
