Abstract

本实用新型涉及改进型激光笔,属物理实验用具,它公开了在激光笔的笔头内增加一段塑料吸管。本实用新型的优点是结构简单但能使光路观察变得很容易,非常适合物理实验使用。

Description

改进型激光笔
技术领域
本实用新型涉及一种激光笔,具体地说是一种可使光斑从一个点变成一条线的改进型激光笔。
背景技术
做物理光学实验时,由于我们通常采用的光源是激光笔,所以,光线较为集中,光斑极为细小,不容易在侧面的白纸上出现路径,导致我们难以观察光路。
发明内容
本实用新型目的在于提供一种改进型激光笔,结构简单但能使光路观察变得很容易,非常适合物理实验使用。
本实用新型的技术解决方案是在现有的激光笔基础上,本实用新型特别是在激光笔的笔头内增加一段塑料吸管。
所述的塑料吸管是圆柱体形状。
本实用新型的工作原理是做物理实验时,按压本改进型激光笔的电源开关,则使原来的线光源变成面光源,光斑也从一个点变成一条线,实践证明,经此改良的激光笔,我们在使用时都能较容易地在白纸上找出入射光线和反射光线。
本实用新型的优点在于结构简单但能使光路观察变得很容易,非常适合物理实验使用。
附图说明
图1是本实用新型的构造示意图。
具体实施方式
根据图1所示,本实用新型包括激光笔笔体1、笔头3和设置在笔头3内的一段圆柱体形状的塑料吸管2。

Claims (2)

1.改进型激光笔,包括激光笔,其特征是在激光笔的笔头内增加一段塑料吸管。
2.根据权利要求1所述的改进型激光笔,其特征是所述的塑料吸管是圆柱体形状。
