| 摘 要： | 利用报废投影机(或幻灯机)上拆下的镜头作为物镜,常用的放大镜作为目镜,再加上数个针对学生理解难点特别设计的屏幕等零件,笔者设计制作了一具尺寸相当大、内部构造一目了然的复式显微镜演示教具,不仅可形象直观地演示显微镜的原理,而且放大倍数足以让人观察到洋葱表皮细胞,还可有助于学生正确理解透镜成像原理、实像与虚像的性质,以及光学仪器之设计构想. |
| 关 键 词： | 复式光学显微镜 成像 透镜 |

| Abstract: | Utilizing a lens removed from a scraped projector(or a slide) as an object lens and a commonly used magnifying glass as an eye pieces,we design and make a compound microscope with a considerable size.Inside the compound microscope,there are several innovative screens specially designed for students to understand some difficult details of the principle of microscope.Internal parts of the compound microscope can be observed clearly.The compound microscope as an educational instrument visually demonstrates how it works.Using this home-made compound microscope with big enough magnification,people can see epidermal cells of an onion.Furthermore,while operating the microscope,students can understand how a lens forms a real image or a virtual image,natures of these images,along with how to design related optical instruments. |
