Abstract: There is provided an optical filter capable of effectively transmitting ultraviolet light in a wavelength range from 220 nm to 225 nm while suppressing the transmission of ultraviolet light in a wavelength range from 240 nm to 320 nm. An optical filter 1 includes a transparent substrate 2 and a dielectric multilayer film 3 provided on the transparent substrate 2 and containing hafnium oxide. A minimum value of spectral transmittance in a wavelength range from 220 nm to 225 nm is 50% or more with an incident angle of 0 degrees, and a maximum value of spectral transmittance in a wavelength range from 240 nm to 320 nm is 5% or less with an incident angle of 0 degrees.

Abstract: Provided is an optical filter capable of reducing the dependency on the angle of light incidence. An optical filter 1 includes a hydrogenated silicon-containing film 4, wherein in a Raman spectrum of the hydrogenated silicon-containing film 4 measured by Raman spectroscopy a ratio (SiH/SiH2) obtained from a ratio between an area of a peak derived from SiH and an area of a peak derived from SiH2 is 0.7 or more.

Abstract: A dielectric multilayer film-incorporated glass plate is disclosed that includes a glass plate and a dielectric multilayer film. The glass plate includes a corner surface located between at least one main surface and a side surface. The dielectric multilayer film includes a main surface covering portion that covers the main surface of the glass plate and a corner surface covering portion that covers the corner surface of the glass plate.
