国产双管显微镜(如JSG型和JBQ-3型显微镜)物镜的结构特点是它的一对物镜做成组合部件。该物镜组一般在出厂前已调整好。但是,出厂后,由于振动、清洗等将破坏原有的调整状态,必须重新调整。本文介绍我在实践中总结的调整步骤: 1.在工作台上放-2mm量块,然后对量块表面调焦,直至在目镜视场中间位置能看到清晰的量块表面像。 2.在目镜中观察狭缝的清晰像是否也位于视场的中间位置。若不在中间位置,则转动
Domestic dual-tube microscope (such as JSG-type and JBQ-3-type microscope) is characterized by the structure of its objective lens made of a combination of components. The objective lens group generally adjusted before leaving the factory. However, after shipping, vibration, cleaning, etc. will destroy the original adjustment status and must be readjusted. This article describes the tuning steps that I’ve summarized in practice: 1. Place a 2-mm block on the workbench and focus the block surface until a clear image of the block surface is visible in the middle of the eyepiece field of view. 2. In the eyepiece to observe whether the slit clear image is also located in the middle of the field of view. If not in the middle, then turn
