产品描述
高放大倍率的变焦透镜系统，用于机器视览/p>
这些变焦透镜机器适合高放大率的机器视觉和成像应用，它们能够良好地在光学性能和大变焦范围之间取得平衡
我们的模块化变焦透镜系统包含一?.7 - 4.5X的变焦镜头（6.5X变焦范围）或一?.58 - 7X的变焦镜头（12X的变焦范围）?.50X?.67X?X?.33X?X伸缩套筒以及可选的0.25X?.5X?.75X?.5X?.0X放大透镜转接件。这些元件组合在一起构?.5X透镜系统后，放大率为0.09 -18，放大调节范围为6.5X，而构?2X系统后，放大率为0.07 - 28，放大调节范围为12X 在调节放大倍率（变焦）时，只需旋转透镜套筒上的旋转环即可，即便透镜安装在V形压块中亦可以调节。请注意，每次只能使用一个放大镜头附加透镜
放大率计箖/strong>
系统的净放大率M（M=像尺?物尺寸）等于放大镜头附加透镜的放大率、变焦透镜（根据实际设置值）的放大率和伸缩套筒的放大率的乘积。例如，如果在放大倍率7X时使?2X变焦镜头?X透镜框和一?X伸缩套筒，系统放大率?72=28、/p>
在使用这些镜头时，我们也提供C-Mount转接件（单独出售），可以兼容我们的C-MountCCD和CMOS相机，或任何其它标准C-Mount相机。我们还提供带一个F卡口安装座的2X伸缩套筒。请注意，变焦透镜必须与一个伸缩套筒一起使用（否则图像不能被聚焦），而放大透镜转接件则是可选用的。另外，使用SM1A9或SM1A10转接件时，本页面所出售的可变焦透镜可以与Thorlabs公司的SM1螺纹光机集成、/p>
?）模块化的变焦透镜系统，用于机器视觉和其它成像应用
??.5X系统可以提供0.09?8.0倍的放大倍率（核心透镜具有6.5倍的放大调节范围
??2X系统可以提供0.07?8.0倍的放大倍率（核心透镜具有12倍的放大调节范围
?）工作距离为36 - 356毫米
?）设计用于我们的C-Mount 2/3英寸传感器式CCD和CMOS相机
?）通过使用SM1A9或SM1A10 C-Mount至SM1转接件与SM1螺纹的元件兼
??.15 - 91毫米的视场（请参看视场标签了解细节）
