NERLITE® 机器视觉光源

暗场照明装置

暗场照明装置

  • 有2种颜色和5种尺寸可供选择
  • 有效,低角度照明
  • 增强表面特征的对比度

暗场照明装置对目标区域提供低角度照明。这些机器视觉光源提高表面特征的对比度,例如激光压印或雕刻的标识,特别适用于如BGA植球,读取激光刻蚀标记或检查表面几何轮廓之类的应用。

暗场照明装置使用一个单一层LED安装在相对于光轴 70º (DF 50 模型)或 90º (DF 100, DF 150-1 模式),或三层LED安装在相对于光轴 75º (DF 150-3 模型)。

  • 二种颜色和五个尺寸
  • 提供有效低角度照明
  • 提高对比表面特征例如激光压印或雕刻标记
  • 高速机器视觉应用具有频闪模式
