| titleOfInvention | Non-Birefringent Optical Resin Material and Optical Member |
| abstract | Provided are an optical resin and an optical member using the same, both orientation birefringence and photoelasticity birefringence of the optical material being deadened and generally eliminated. The optical material consists of a composite constituent system of three or more constituents including a copolymerization system of monomer-element number not smaller than two, combination and constituent ratio of the composite constituent system being set so that both orientation birefringence and photoelasticity birefringence of the optical material are deadened at the same time and 5.0×10 −5 or less is given under a condition that principal chains of the copolymerization system have degree of orientation equal to 0.03, and further a photoelasticity constant not greater than 1.0×10 −12 (Pa −1 ) is obtained. The composite constituent system may contain an additive containing a low molecular weight compound which has an anisotropic polarizability and can be orientated in a polymer. The composite constituent system may consist of a copolymerization system of monomer-element number not smaller than three. Optical members produced by applying molding to the optical hardly show birefringence if external force is applied. |
