通常，窄带光源被用作激发光源。某些波长范围是激光所无法覆盖的，这时窄带光源的作用就非常大了。一些原子谱线辐射灯也被用作波长校准标准源。
结合单色仪和宽带光源，Spectral Product制作了连续可调的窄带光源。输出带宽由单色仪所用狭缝宽度和光栅刻线密度决定，通常在1-20nm。
Spectral Products提供多款基于氘灯的可调窄带光源。每个型号都是在CM110双光栅，1/8-米单色仪的基础上， 结合一款Spectral Products的30W深紫外光源组成。
这类可调窄带光源的特点：
输出可以在紫外180 - 400 nm间选择
通过RS232接口，由计算机控制
可双向扫描，可以纳米、埃、微米、波数或电子伏特eV为单位扫描
可配置为优化的光纤照明
模块化设计，可再配置
可匹配其它Spectral Products 产品
Narrow-band light source: Deuterium Based
Simple, Flexible
Spectral Products has a tunable light source to meet your needs. Each model is based on our popular CM110 dual grating, 1/8-meter monochromator, paired with one of Spectral Products\' deep UV 30W deuterium light sources.
Models:
Band-pass region and width is controlled by selection of monochromator slit size and gratings.
