前言近二十年来,随着光栅刻划和复制技术的发展,光栅单色仪已广泛地应用于光谱分析中。在国外,光栅单色仪已有较完整的系列。国内一些科研单位和工厂也先后研制出不少型号的平面光栅单色仪。近年来激光全息技术在光栅制造上的应用已经进入商品阶段,因此研制和生产全息凹面光栅单色仪的任务就提到日程上来了。用全息凹面光栅比用普通的平面衍射光栅制造单色仪具有很多优越性。凹面光栅除具有
Introduction Nearly two decades, with the development of grating characterization and replication techniques, grating monochromators have been widely used in spectral analysis. Abroad, grating monochrometer has a more complete series. Some domestic research institutes and factories have also developed many models of flat grating monochromator. In recent years, the application of laser holographic technology in grating manufacturing has entered the commodity stage, so the task of developing and producing holographic concave grating monochromator is mentioned on the schedule. Holographic concave gratings have many advantages over monochromators using ordinary planar diffraction gratings. Concave grating except with
