基于分光计的光栅光谱特性研究
|
摘要
在分光计上,观察并测试了不同光栅常数的光栅在汞光源下的光谱,探究光栅的分辨能力与光栅常数之间的关系。实验结果表明,在光栅有效使用宽度一定的情况下,随着光栅常数的减小,光栅的色分辨本领R和角色散率D都大幅提高,光栅的分辨能力提高。因此,在技术许可的条件下,减少光栅常数d是提高光栅色分辨本领的有效措施,这对光栅的制作和选用以及相关领域的发展具有较好的指导作用。
In the experiment using the spectrometer to observe and test the spectra of different grating constant of the grating under the mercury source to explore the relationship between resolution capabilities of a grating with the grating constant. The results show that in the case of the effective use of the width of the grating is under the same circumstances,with the decrease of the grating constant the chromatic resolving power R and angular dispersion rate D of the grating are greatly improved and the resolution capability of grating are improved.Therefore,under the permissibility of technique condition,reducing the grating constant d is an effective measure to improve the chromatic resolving power of grating. It is a better guiding role to promote the production and selection of the grating and the development of related fields.
