  • Patent number: 9022571
    Abstract: An optical device includes: a light transmissive first substrate; a light transmissive second substrate; a polarizing layer disposed between the first substrate and the second substrate; a first bonding layer which bonds the first substrate to the polarizing layer; and a second bonding layer which bonds the second substrate to the polarizing layer, wherein the first bonding layer is an adhesive layer, and the second bonding layer contains a structure of siloxane (Si—O) and a leaving group. By forming the first bonding layer of an adhesive layer, a necessary strength can be ensured, and also the optical properties can be enhanced by absorbing the irregularities of the polarizing layer formed of a synthetic resin so as to prevent the contamination with air bubbles. Since the time of exposure of the polarizing layer to heat generated by a plasma can be decreased, the polarizing layer is not deteriorated.

  • Publication number: 20080026216
    Abstract: An adhesive tape which is to be arranged between a lens and at least one of a plurality of chucks in an edge-machining apparatus comprises an adhesive face for being in contact with the lens. A measurement of an adhesive strength of the adhesive face is 4 gf (0.0392 N) or more when a polyethylene terephthalate plate which has been subjected to a surface treatment with a fluorine-modified silicone parting agent is used as a test plate in an adhesive strength test method based on a 180°-peeling method as defined in JIS Z 0237 “adhesive tape/adhesive sheet test method”. A technique which can be used to edge the lens in which an antifouling layer is formed by using a fluorine-containing silane compound having an excellent antifouling effect is also provided.
