Title:
OPTICAL MOLDED ARTICLE COMPRISING RESIN MATERIAL CONTAINING CYCLIC OLEFIN ADDITION POLYMER
Document Type and Number:
Japanese Patent JP2009227840
Kind Code:
A
Abstract:
To provide an optical molded article which is obtained by using a resin material containing a cyclic olefin addition polymer, whose part to be irradiated does not become clouded and is not deteriorated in transparency even when irradiated with blue-purple laser light having 390-430 nm oscillation wavelength over a long time with high irradiation intensity and the mechanical properties and optical properties of which are restrained satisfactorily from being deteriorated.
The optical molded article comprising the resin material containing the cyclic olefin addition polymer is characterized in that the cyclic olefin addition polymer has 15 ppb metallic element Fe content.
