Abstract:
1. An optical lens comprising a molded body made of a molding material containing a transparent polyamide cross-linked through irradiation with radioactive rays and a stabilizer, said optical lens having total light transmittance of at least 60% when said molded body has a thickness of 2 mm, and having total light transmittance of at least 50% after said molded body maintained at 80° C. is irradiated with light in an amount of 1000 W/m said transparent polyamide is composed of a condensation polymer of 1,10-decanedicarboxylic acid and 3,3′-dimethyl-4,4′-diaminodicyclohexylmethane, a blend ratio of said stabilizer being 0.01 to 0.21 parts by weight with respect to 100 parts by weight said transparent polyamide, and said stabilizer including 2-methyl-6-ethyl-hydroquinone.
