Provided is a light transmitting member, which maintains an antifogging property over a long period of time, and is less liable to be contaminated with organic matter, the light transmitting member including, on a base material, a porous layer containing silicon oxide particles and a layer formed of a hydrophilic polymer, wherein a polymer ratio at a depth of 10 nm from a surface of the light transmitting member is 0.15 or more and 0.40 or less.

Light transmitting member and method of producing the same

A light-transmitting member includes a substrate including a resin layer, and a functional film disposed on the substrate. The substrate has a thickness of 1 μm or more and less than 1 mm. An optical thickness of the functional film with respect to light having a wavelength of 464 nm or more and 653 nm or less is less than a half of the wavelength. A contact angle of water with respect to an upper surface of the functional film in the light-transmitting member is less than 90°. The functional film has a porous portion containing a plurality of particles. A first particle and a second particle among the plurality of particles are bound to each other with a binder. Each of the first particle, the second particle, and the binder contains an inorganic material.

Light-transmitting member and shield

Provided is a light transmitting member including: a base material; a first porous layer formed on a first surface of a base material; and a second porous layer formed on a second surface opposed to the first surface of the base material, wherein the second porous layer has a pore volume larger than a pore volume of the first porous layer.

Light transmitting member, transparent protective cover, and image pickup system

The present disclosure provides a member having a porous layer containing particles and having a low refractive index and high film strength and a coating liquid for forming a porous layer containing particles, wherein the porous layer contains a plurality of silicon oxide particles bound by an inorganic binder and at least one acid.
