The utility model provides an optical demonstration instrument for presenting a space light path, which relates to the teaching aid field. The existing optical teaching aids are not intuitive enough to demonstrate the optical path, and there is a problem of insufficient accuracy. The utility model discloses an optical demonstrator for displaying a space light path, comprising a light source, a transparent light path display device filled with smoke or a glycerin doped with iron filings, and light emitted by the light source through the transparent light path display device. The optical demonstrator show space optical path, including experimental apparatus, experimental apparatus is fixed on the transparent light path display device, including the dial plane mirror, uneven lens or concave lens and a convex lens and a convex mirror, concave lens or prism, three glass brick. The utility model can observe the light transmitting to the material surface or the propagation path of the light beam through the transparent object under the natural light, and the teaching effect is good and the accuracy is controllable.

呈现空间光路的光学演示仪
本技术涉及教学教具领域,尤指能够呈现空间光路的光学演示仪。技术背景光在透明物质中传播的路径很难被观测到,学生在学习光学知识的过程中,对 光束的传播路径不易产生直观的印象,因此需要进行试验演示。现有的实验教具多是针 对某一项演示内容而制作的,如呈现光的反射路径的实验,是通过一个平面的漫反射来 观看的,其实验的难度比较大,且不稳定、直观。又如呈现光在水中传播路径的实验, 是通过在水中滴几点墨水,以使光线的光路在墨水中清晰可见,其现象很不明显,而且 要求教室的光比较暗,眼睛离水槽比较近才能观看。另外,对于呈现光在气体中沿直线 传播的路径;呈现光的镜面反射和漫反射传播的路径;呈现光从空气斜射入水中折射前 后光路;呈现光束通过凸面镜、凹面镜、凸透镜、凹透镜的空间光路;呈现光束通过三 棱镜、玻璃砖的空间光路等教学内容的演示仪器还很缺乏,多由学校自行采购、制作, 不能保证精度,不利于教学的推广。
