  A non-birefringence optical resin material is obtained by forming a transparent matrix from a polymeric resin having an orientation birefringence with a positive or negative sign, adding a low molecular weight substance exhibiting an orientation birefringence with a sign opposite to that of the orientation birefringence of the polymeric resin for the matrix and thus offsetting the orientation birefringence of the polymeric resin for the matrix with the orientation birefringence of the low molecular weight substance.

  一种非双折射光学树脂材料是通过以下方法获得的：将具有正负号取向双折射的聚合树脂制成透明基体，然后加入一种低分子量物质，其取向双折射的符号与基体聚合树脂的取向双折射相反，从而用低分子量物质的取向双折射抵消基体聚合树脂的取向双折射。
