    摘要: An optical member includes a transparent substrate containing at least one substance selected from glass, a glass ceramic, silicon, and sapphire, and having an infrared high-transmittance region in which an optical transmittance is 78% or more in a wavelength band of 700 nm to 1800 nm; and an optical interference film disposed on a main surface of the transparent substrate corresponding to the infrared high-transmittance region, wherein a transmittance of light, of the optical member, of at least one wavelength λ s in the wavelength band of 700 nm to 1800 nm in a region of the optical member corresponding to the infrared high-transmittance region of the transparent substrate has a minimum value of 86.5% or more and has a difference between the minimum value and a maximum value of 9% or less in a range where an incidence angle is from 0 degrees to 60 degrees.

    摘要: The present invention provides a glass laminate in which a thin inorganic laminated film having a thickness of 500 nm or less is laminated on the surface of a glass plate and it is possible to suppress a poor appearance such as cracks of the inorganic laminated film during manufacturing and attachment of dust to the surface of the inorganic laminated film during use. A glass laminate (1), in which an inorganic laminated film (30) having a total thickness of 90 to 500 nm is laminated on a surface of a glass plate (10) with an adhesive film (20) including a resin film interposed therebetween, a carbon-containing film (42R) thinner than the inorganic laminated film (30) is attached to a surface of the inorganic laminated film (30), a storage elastic modulus of an outermost surface on the inorganic laminated film (30) side that is measured by a nanoindentation method using a flat punch indenter under conditions of 1 Hz and 28°C is 50 MPa to 30 GPa, and a loss coefficient of the outermost surface on the inorganic laminated film (30) side that is measured by the nanoindentation method using the flat punch indenter under conditions of 1 Hz and 28°C is 0.005 to 0.14.
