Navitar远心镜头
远心镜头最重要的优点之一是物体距离变化并不影响图像的放大倍率。远心镜头从相同的视角来观察和显示整个物体,因此,不会出现类似使用标准镜头时三维特征出现的透视变形和图像位置错误。即使在深孔内部的物体,在整个视野中也清晰可见,因此,在检测三维物体时或当图像尺寸和形状精确性十分重要的情况下,远心镜头非常有用。
12 倍远心
12 倍远心变焦系统允许用户在小于 0.3° 的情况下,仍能保持恒定的视角和放大倍率,达到一种真正的远心状态。此镜头应用广泛,可以应用于物体的精确测量和模板识别。
双面远心
Navitar 双面远心镜头在物体和图像位面两方面都具有远心特性,图像失真率小于 0.1%,不会产生视差错误和图像虚光。
Navitar 提供一系列高性能的远心镜头,可用于机器视觉、测量学和精密测定等应用中。该系列镜头全部具有低光学失真率和高度聚焦远心特征,可完美和精确地再现图像,尤其是在观察三维物体时。 Navitar 双侧远心镜头(Double-Sided Telecentric)系列型号如下所示:
