摘要
本设计是一个可以通过更换不同放大倍数的目镜来观看从而获得不同放大倍数的图像的一个仪器,此设计属于光学机械仪器的设计,数码观靶镜在生活中可能见得比较少,它的整体结构可以大致分为三大部分,第一部分:镜筒前端物镜;第二部分:镜筒末端目镜;第三部分:棱镜。镜筒前端内部主要有一些镜片,通过隔圈连接的2个镜片可以把光束传递到镜筒中,镜片的主要靠衬套以及密封圈来固定的。远处的景物通过前组物镜成一个倒像位于施密特棱镜前。经过施密特棱镜将中间像翻转135度后,使用者再通过目镜观察。其中有个最重要的零件(棱镜),这个施密特棱镜把镜筒前端传递的光束经过三次全反射从而实现将倒像正立并折转45度以便于观察者使用。然后通过第三部分的目镜看到放大的图像,本次设计的难点在于怎样控制好棱镜的定位,我设计了一个拉杆,通过一个链接是二个杆子链接起来,二杆固定在镜筒末端的筒壁上,这样可以通过铰链使二杆固定好棱镜。使得棱镜的中心线和目镜的中心线重合或者平行。这样光束能够大部分的通过棱镜到达目镜中。

Abstract
The design is can be replaced by different magnification of the eyepiece to watch to obtain different magnification of the image of an instrument, the design of optical and mechanical equipment design, digital spotting scope in life may be less, the whole structure can be divided into three parts, the first part: the front end of the lens barrel lens; part second: barrel end eyepiece; part third: prism. The front end of the lens barrel inside some lenses, through a spacer ring is connected to the 2lens can put the light beam is passed into the barrel, lens depends mainly on the bushing and a sealing ring fixed. The distant scene through the front group lens into an image in Schmidt prism before. After Schmidt prism in the middle like flip135 degrees, then the user through the eyepiece. One of the most important parts, the Schmidt prism to the beam passes through the front end of the lens barrel three times t
