近年来我国引进了许多西德Leitz厂生产的MM6大视场金相显微镜,由于该机无摄影编号装置,因此拍摄后的底片易互相搞错。为了避免这一缺点,本文介绍一种自制的附加简易装置,它适用于拍摄4吋底片的编号。经实践应用,该装置使用方便、经济实用,而且对原机毫无损坏。下面就该装置的制造和使用作一简介。 1 编号装置及其制造图1即为该装置的立体图。取2毫米厚的黑色有机玻璃(或木板),截成47×47毫米方块,然后在图1所示的右上角切除9×9毫米。另取10×10毫米的有机玻璃(或木条)一根,截成长37毫米的两根,分别粘在如 In recent years, China introduced a number of West Germany Leitz plant MM6 large field metallurgical microscope, as the aircraft no photographic numbering device, so the film after filming easy to make mistakes each other. In order to avoid this disadvantage, this article describes a self-made additional simple device, it is suitable for shooting 4-inch film number. The practical application of the device easy to use, economical and practical, and the original machine without damage. The following is a brief introduction to the manufacture and use of this device. 1 Numbering device and its manufacture Figure 1 is a perspective view of the device. Take 2mm thick black plexiglass (or wood), cut into 47 × 47mm square, and then cut off 9 × 9mm in the upper right corner shown in Figure 1. Another take 10 × 10 mm plexiglass (or wood) one, cut into two 37 mm, respectively, such as sticky
