Provided is a polycarbonate resin which maintains favorable properties as an optical material while having fluidity suitable for molding. Furthermore, provided are an optical lens and an optical film that use the polycarbonate resin. The polycarbonate resin is characterized by comprising a component unit (A) expressed by general formula (1) and a component unit (B) expressed by general formula (2).

Polycarbonate resin, and optical lens and optical film using same

A thermoplastic resin composition that cuts visible light and has infrared light transmittance. A thermoplastic resin composition including a thermoplastic resin and a coloring material, wherein the refractive index at a wavelength of 894 nm is 1.60 or greater, and when the thickness of the thermoplastic resin composition is 1 mm, the maximum value of the transmittance of wavelengths of 380 nm-630 nm is greater than 0% and less than or equal to 1.00%, and the average transmittance of wavelengths of 840 nm-940 nm is greater than or equal to 80%.

Thermoplastic resin composition and optical member using same

Provided is an optical resin composition for lenses that contains a resin having a structural unit represented by formula (1), and a binaphthalene compound and/or a binaphthalene compound oligomer having a structural unit represented by formula (2). A, p, K, K, Z, and q in formula (1) are as described in the present specification. R-R, a, and b in formula (2) are as described in the present specification.

Resin composition, molded body, optical lens, and optical lens unit

Provided is an optical lens formed by integrally molding a lens part that is an optically effective portion and has a light incidence/emission surface, and a lens edge part that is an optically ineffective portion and has a surface thereof except the light incidence/emission surface. The lens edge part includes a non-transparent region in part or all thereof, the lens part and the lens edge part include a thermoplastic resin, and the non-transparent region in the lens edge part contains a total of 0.1-5 mass % of one or more of a black dye and a black pigment.
