Abstract:
PROBLEM TO BE SOLVED: To minimize the birefringence and limit a deformation due to environ mental changes by press-molding performs after preliminarily molding a thermo plastic resin with a saturated hydrocarbon ring into the preforms of prism. SOLUTION: Preforms 2a of prism which are of an almost approximate shape to the shape of an article of manufacture are formed by injection-molding an optical thermoplastic resin, preferably a thermoplastic resin with a main chain or a lateral chain having a saturated hydrocarbon ring. Further, these performs 2a are thermally molded under pressure using a specified mold and only the surface layer is melted and further, the prereforms 2a are press-molded to be shaped into prism articles of manufacture. Although the preforms of prism 2a to be obtained by injection molding need not be shaped to the accuracy which is too strict, the extremely inferior accuracy of the face results in the generation of an air pent-up in the surface of moldings during press-molding and the resultant extra labor required for enhancing the face accuracy. For these reasons, it is advisable to reject the preforms 2a with the extremely inferior face accuracy and also obtain the preforms 2a with a press allowance (t) when the preforms 2a are press-molded.
