Abstract

The development of a computer-controlled spectrophotometer that enables measurement of spectral transmittance, reflectance, and optical loss of thin-film specimens is discussed. We also describe the design and testing procedure of the spectrophotometer, incorporating test sample performance data. In the visible region the overall photometric accuracy is verified to be 0.1% and 0.2% for transmittance and reflectance, respectively. The wavelength scale is accurate to within 0.5 nm with a reproducibility of 0.1 nm.

摘要

本文讨论了一种计算机控制的分光光度计的开发，该分光光度计能够测量薄膜样品的光谱透射率、反射率和光学损耗。我们还描述了该分光光度计的设计和测试程序，并纳入了测试样品的性能数据。在可见光区域，透射率和反射率的整体光度测量精度分别验证为0.1%和0.2%。波长刻度的精度在0.5 nm以内，重现性为0.1 nm。
