An optical matching oil that is immune to timewise variations in its refractive index, that undergoes little increase in viscosity below room temperature, and that also resists crystallization below room temperature. The optical matching oil is based on an organosilicon compound with the following general formula ##STR1## wherein R is selected from the group consisting of methyl, vinyl, and 2-methylphenethyl with the proviso that at least one R group is the 2-methylphenethyl group.
一种光学匹配油,其抗折射率随时间变化的能力较强,低于室温时粘度增加很少,并且在室温以下也能抵抗结晶。该光学匹配油基于一种
有机硅化合物,其通式如下:##STR1## 其中R选自甲基、
乙烯基和2-甲基苯乙基等组成的群体,但至少一个R基为2-甲基苯乙基。
