针对低色散玻璃H-FK61色散值小,变化范围窄(通常为十万分之六),对测量要求比较严格的情况,推导了三最小偏向角法的数学公式,对比分析了该方法与最小偏向角法的测量精度情况,得出在同等条件下三最小偏向角法精度优于最小偏向角法的结论,用现有精密测角仪(±1″)验证了以上结论,并解决了H-FK61色散的高精度测量问题,同时也为FCD100(色散更低)玻璃的色散测量奠定了基础.

As to the low dispersion glass H-FK61, the dispersion value is small, and its variation range is narrow, which have a very strict requirement to the measuring method. Under such circumstances, the formulae of three minimum angles of deviation are derived, and its accuracy is analyzed in comparison with traditional minimum angle of deviation method. The analysis shows that under the same condition, the accuracy of three minimum angle of deviation is higher than that of the minimum angle of deviation. Finally, we verify it at the goniometer, and solve the measuring problem of H-FK61, which lay a foundation for the measuring of another special glass FCD100.
