我们通过实验评估了使用常用波长计在近红外区域测量的频率的准确性，并在可见光区域进行了校准。尽管目录中规定的精度为 20 MHz，但使用波长计在近红外区域进行频率测量时观察到约 50 MHz 的误差。该误差是由于波长计斐索干涉仪内残留水分造成的。提出了一种避免该错误的简单方法。
We have experimentally evaluated the accuracy of the frequency measured using a commonly used wavelength meter in the near-infrared region, which was calibrated in the visible region. An error of approximately 50 MHz was observed in the frequency measurement using the wavelength meter in the near-infrared region although the accuracy specified in the catalogue was 20 MHz. This error was attributable to residual moisture inside the Fizeau interferometer of the wavelength meter. A simple method to avoid the error is proposed.
