Abstract

易聚焦自准直望远镜，包括物镜筒、销轴、圆筒和镜框，其特征在于：在物镜筒下面设置有与物镜筒身平行的圆筒，销轴穿过圆筒后通过插销与镜框活动连接，镜框内镶嵌有平面镜镜面。使用时，打开望远镜镜筒内的照明小灯，将平面镜面上转堵住物镜筒，伸缩目镜筒，从目镜中能观察到经平面镜镜面垂直反射回来的光线，直至形成清晰的绿十字像。本发明的有益效果是，既简单方便又实用美观，能提高实验效率，且易于生产。

Description

易聚焦自准直望远镜
技术领域
本发明属于物理实验仪器领域，涉及一种易聚焦自准直望远镜。
背景技术
在做有关分光计实验时，必须先调好分光计，其中关键的步骤是寻找从放置在载物台上平面镜反射回来的绿十字像。由于目镜筒中的十字物一般不会正好位于物镜的焦平面上，最好的情况是看到反射回来的是一团绿，因为绿团较淡，不易发现，使实验无法进行。
发明内容
为了解决存在的问题，本发明的目的是提供一种易聚焦自准直望远镜，能方便快速地调出绿十字像。
本发明解决其技术问题所采用的技术方案是：易聚焦自准直望远镜，包括物镜筒、销轴、圆筒和镜框，其特征在于：在物镜筒下面设置有与物镜筒身平行的圆筒，销轴穿过圆筒后通过插销与镜框活动连接，镜框内镶嵌有平面镜镜面。
使用时，打开望远镜镜筒内的照明小灯，将平面镜面上转堵住物镜筒，伸缩目镜筒，从目镜中能观察到经平面镜镜面垂直反射回来的光线，直至形成清晰的绿十字像。
本发明的有益效果是，既简单方便又实用美观，能提高实验效率，且易于生产。

图2为本发明平面镜立体图。
图中：1-镜筒2-销轴3-圆筒4-镜框5-物镜筒21-插销22-平面镜镜面
具体实施方式
下面结合附图对本发明做进一步详细的说明：
如图1、图2所示，本发明易聚焦自准直望远镜，包括物镜筒5，销轴2，圆筒3，镜框4，其特征在于：在物镜筒5下面设置有与物镜筒身平行的圆筒3，销轴2穿过圆筒3后通过插销21与镜框4活动连接，镜框4内镶嵌有平面镜镜面22。
使用时，打开望远镜镜筒内的照明小灯，将平面镜面22上转堵住物镜筒5，伸缩目镜筒，从目镜中能观察到经平面镜镜面22垂直反射回来的光线，直至形成清晰的绿十字像。
