Camera and System Integration
The C-Mount interface and support for sensor formats up to 2/3 inch make the PMS-LZL-12100 suitable for integration with a wide range of industrial area-scan cameras.
Browse POMEAS industrial machine vision cameras for compatible camera options. The selected camera sensor should not exceed the maximum image format supported by the lens.
Camera sensor size, pixel size, resolution, required field of view, working distance, smallest inspection feature and required inspection accuracy should be evaluated together when configuring the imaging system.
Manual Continuous Zoom vs Detented Zoom
The PMS-LZL-12100 provides free manual continuous adjustment throughout the 0.58X–7.5X magnification range. This is useful when engineers need maximum flexibility to adjust the field of view and magnification according to different inspection targets.
For applications that require operators to return repeatedly to predefined magnification positions, consider the PMS-LZL-12100D15 12.5X detented zoom lens , which provides 15 mechanical detent positions for improved zoom-position repeatability.
