A dust-proof, light-transmitting member disposed on a light-receiving surface of an imaging device, comprising a light-transmitting substrate, at least a light-entering surface of which is provided with a dust-proof coating having fine roughness on the surface.
摘要:
An apparatus for forming an optical film on a curved-surface, optically effective portion of a pickup lens having the optically effective portion and a circumferential flange, comprising a rotatable jig for fixedly holding the pickup lens, an apparatus for rotating the jig, a case rotatably supporting the jig, and a nozzle for spraying or dropping a coating solution containing an optical-film-forming component onto the pickup lens; the jig comprising a columnar table and a hollow cylindrical cover, the hollow cylindrical cover comprising tabs extending inward from an upper end of a cylindrical portion for fixedly holding the flange, and the coating solution being sprayed or dropped onto the optically effective portion, while rotating the jig at a rotation speed of 8,000 rpm or more with the deviation of rotation axis of 50 μm or less.
摘要:
An apparatus for forming an optical film on an optical substrate is provided. The apparatus may include a rotatable jig for fixedly holding the optical substrate, an apparatus for rotating the jig, and a nozzle for dispensing a coating solution containing an optical-film-forming component onto the optical substrate. A rotation speed of the jig may be 8,000 rpm or more, and a deviation of rotation axis of the jig may be 50 μm or less.
摘要:
An optical element comprising a lens having a portion with a surface inclination angle of 50° or more within an effective-diameter region, the portion being 10% or more of the effective-diameter region in a projected area, and an anti-reflection coating formed on the lens, the anti-reflection coating having fine roughness with three-dimensional average surface roughness of 5-100 nm on the surface.

摘要:
A silica aerogel coating is produced by reacting a wet gel obtained by the hydrolysis and polymerization of alkoxysilane with an organic-modifying agent to form organically modified silica, dispersing the organically modified silica by an ultrasonic treatment to form an organically modified silica dispersion, adding an ultraviolet-curable resin and a photo-polymerization initiator to the dispersion to prepare a coating liquid, applying the coating liquid to a substrate, and then irradiating ultraviolet rays to the coated layer.
