A high-accuracy spectrophotometer, originally designed for work at visible wavelengths, was modified to permit measurements in the ultraviolet without degradation of its original performance. This was accomplished by equipping the spectrophotometer with a stable deuterium arc source, a highly efficient averaging sphere with fluorescent wavelength converter, a new grating, and achromatic sample-compartment optics. The modified spectrophotometer will be used for the development of new Standard Reference Materials, as well as for materials research, in the region between 200 and 300 nm.
一台最初设计用于可见光波长工作的高精度分光光度计经过改装，以允许在紫外光区进行测量而不降低其原有性能。这是通过为分光光度计配备一个稳定的氘弧光源、一个带有荧光波长转换器的高效积分球、一块新光栅以及消色差样品室光学元件来实现的。改装后的分光光度计将用于在200至300纳米区域开发新的标准参考物质以及进行材料研究。
