Title:
THERMOPLASTIC RESIN MATERIAL AND OPTICAL ELEMENT MADE THEREOF
Document Type and Number:
Japanese Patent JP2005325349
Kind Code:
A
Abstract:
To provide a thermoplastic resin material having extremely small refractive index variation with temperature and provide an optical element produced by using the material.
The thermoplastic resin material contains surface-treated inorganic fine particles having an average particle diameter of ≥1 nm and ≤30 nm and dispersed in a host material composed of an organic polymer and has an absolute value of the temperature-dependency of refractive index |dn/dT| satisfying the formula (A): 0≤|dn/dT|≤5.0×10-5.
