摘要
浸液-干涉法测量透镜的折射率是将被测透镜置于充有折射液的容器内,通过配液使混合液的折射率与被测透镜的折射率尽可能接近一致,并用干涉法来确定这种一致性。然后通过测量混合液的折射率,从而间接得知透镜折射率的测量方法。这种测量方法很容易达到±1×10^(-4)的精度。
The measurement of lens refractivity with immersion-interferometer method is that a lens to be used is placed in a container filled up with refractive liquid, the refractivity of which is made possibly to be approximateiy coincient with that of the measured lens through mixing liquids, and the coincidence is determined by interferometer method. The refractivity of the lens is then known indirectly through measurement of the refractivity of the mixed liquid. This measuring method can easily result in an accuracy of ±1×10^(-4).
