二手BX61，BX60全自动系统金相显微镜 特价现货转售

·诺曼尔斯基微分干涉衬比法系统提供限度可视度 
用诺曼尔斯基微分干涉衬比法观察，现已被认为检验材料、金属和半导体结构不可缺少的手段。为了确保适合于各种样品具体状态的分辩率和对比度，奥林巴斯提供三种不同类型的棱镜：即用于通用检验的U-DICR；用于对精细结构的高分辩率检验的U-DICRJ；用于高对比度检验的U-DICRHC。每一种棱镜可单独使用，且易于更换，易于使用。

·超高放大倍数观察 
BX2M-RLA2明/暗视察法用反射光照明装置备有高功能孔径光阑，它可以将孔径连续缩小到超高倍率观察所需要的针孔大小。这种特性提供焦深很深的高对比度观察象，又专门备有150倍和250倍的超高率复消色差物镜。而且物镜具有特长的工作距离，有助于避免观察中物镜顶端与样品碰撞。

·暗视野法的观察象亮度增到已往的两倍 
奥林巴斯改进了聚光功能，使暗视野法的观察象亮度比已往系统几乎大两倍。因此，微小的缺陷、极小细节和细微杂质均能清晰地检测到。

·适用于成象的平场复消色差物镜 
使用色差完全被消除的高分辩率物镜，就能得到某些结构对比度、清晰度、分辩率均高的观察象，例如靠近光学分辩极限的半导体几何图形。

2、镜体形状设计的改进促使人机工程学进一步改善

·更为紧凑的Y形镜体设计使操作更舒适 
新显微镜的镜体长度减少，从而为奥林巴斯的Y形造形设计提供了更为宽绰的工作空间。由于照明灯壳小型化，镜体变得更为紧凑，减少显微镜的占用空间，便于在镜体附近的自由桌面上放置样品和辅助装置，不会妨碍操作员的工作。 
·操作部位布局合理 
大量减轻长时间观察中的疲劳 
作为很少感到疲劳而颇受广大用户好评的Y形镜体，经过新的精心设计其操作舒适性进一步提高。操作员能将前臂放在桌面上随意完成所有调焦和载物台操作，即使复杂的观察也不必频繁移动手臂和手腕，手部运动量很小。

·调焦操作轻而易举 
新微调旋钮易于换装到左右任何一边 
新调焦微调旋钮可以拆卸下来换装到显微镜的左右任何一边，以适合操作员喜好。控制旋钮的覆盖层因微动灵敏度高而易于用手指肚儿轻摸操作，即使在高放大倍率下进行微调也非常。

·可倾斜镜筒系列能使操作员维持舒适姿势 
U-TBI和U-ETBI可倾斜镜筒是供双目观察的，而U-ETTR镜筒是供讨论或显微照相需要的。本系列镜筒能让每个操作员选择适合的眼点位置和人机工程学姿势，从而大量减轻长时间观察中的疲劳。
