在碳弧前面放一个滤光片就可以得到令人满意的近单色光。
The monochromatic photocurrent of photocathode actually reflects its quantum yield under the monochromatic light.多碱光电阴极的单色光电流实质上反映的是其在该单色光照射下的量子产额。
A red highlight LED was used as quasi-monochromatic light source for analyzing the diffraction property of an axicon in quasi-monochromatic light.为了分析准单色光照射轴锥镜的衍射特性,用红色高亮发光二极管作为准单色光源。
