【技术实现步骤摘要】
一体化双缝干涉仪
本技术涉及光学实验领域的一种干涉仪。
技术介绍
用双缝干涉仪测光的波长,是人教版普通高中课程3-4教材中一个重要的学生分组实验,该实验在实际教学过程中存在两个方面的困难,一是组装调试繁琐费时,每次做该实验前,都需要十余人全部参与25组仪器的组装调试,需要整整两个小时才能满足教学要求;二是由于所用的光源是12伏的小灯泡,亮度低,干涉图样不清晰甚至调试不出来,导致实验效果很不理想。另外,在实际教学中,调试好的仪器经过一个班的学生实验操作后,很多仪器的干涉图样就观察不到了,需要重新调试,当两个班的课连排时,中间就没有调试时间,给教学带来很难解决的现实问题。
技术实现思路
本技术的目的是提供一种一体化双缝干涉仪,免除原仪器组装、调试的繁琐过程,提高干涉条纹的亮度,使测量更加方便,从而极大提升实验教学效果。本技术的技术方案是:一体化双缝干涉仪,包括一个盒体,其特征是,在盒体后侧壁固定有放光装置,在盒体前侧壁固定有测量装置,在盒体中间通过支架固定有遮光筒;其中放光装置由电池盒、LED光源 ...
