徕卡DM2500 M金相显微镜适用于钢铁,金属,化工材料行业科研, 质检, 质控部门等研究,反射光可实现明场, 暗场,偏光,微分干涉,荧光观察功能,透射光可实现明场, 暗场,偏光,微分干涉观察功能,可接CCD相机配合图像分析软件进行材料分析。
一、Leica DM2500 M金相显微镜(德国徕卡全手动正置型)主要特点
1、可选配带角度调节的目镜筒,大大降低操作者的疲劳。
2、目镜视野直径22mm。
3、物镜直径32mm,使光通量提高了40%,拥有更高的分辨率和景深。
4、物镜转换手动控制。
5、可升级选配变倍器,有1.5X、1.6X、2X三种可选。
6、明场、暗场、偏光、干涉观察方式手动转换。
7、孔径光阑档位与物镜倍数对应,以不同颜色精确标记,更快速恢复工作状态, 视场光阑档位与目镜的视野数对应,另有暗场档位,相机靶面尺寸档位。
8、机身采用反向温度补偿技术,有效降低了因发热造成的焦平面漂移。
9、具有4位滤色镜架插槽,可以同时插入四种不同色的滤色镜在待插入位置,既随时推入拉出,有可防灰尘进入光路。
10、具有聚焦高度限位装置,防止样品碰到物镜。
11、可选配徕卡原装显微镜数码成像装置,实现全部的本厂配置,达到整体和谐。
12、可选配徕卡各种图像处理及分析软件,包括景深扩展软件,通用图像分析软件,金相分析软件。
13、可接干涉台阶仪进行高精度测量;
14、可接大尺寸物台用于半导体检测;
15、可升级为其他观察方法。
