Why Different Focusing Methods Matter

Different vision applications place different demands on image sharpness and field-of-view performance. Optimizing focus at a single center point may be sufficient for some systems, while others require balanced sharpness across the frame or precise optical alignment.

FRAMOS applies the appropriate focusing method based on the lens, resolution, and application requirements to ensure consistent and repeatable image performance.

  • Application-specific focus requirements across the image
  • Optical tolerances between the sensor, lens, and mechanics
  • Consistent image performance across production units
  • Balancing cost, imaging performance, and production volume when choosing the right focusing approach
Why Different Focusing Methods Matter

Choose the right focusing approach

FRAMOS provides multiple focusing methods to deliver the right balance of sharpness, consistency, and production repeatability.

  • CentER focusing

    Center Focusing optimizes sharpness at the center of the image where the primary subject is typically located. During the focusing process, measurements are taken at the central region to ensure reliable image clarity where it matters most. This approach provides a practical and efficient focusing method for many embedded vision applications.

    • Lowest complexity and cost, ideal for applications with a defined region of interest
    • Best suited for lower volume projects and flexible deployment needs

  • Multi Region Focusing

    Multi-Region Focusing evaluates several areas of the image during the focusing process to balance sharpness across the usable field of view. Instead of optimizing only a single center point, this method measures multiple regions to achieve more uniform image performance across the frame. It is well suited for applications that require reliable image clarity beyond the center, such as inspection, detection, and wide-scene vision systems.

    • Balanced cost and performance, improving image consistency across the full field of view
    • Scales across mid-volume deployments requiring consistent image quality

  • Active optical alignment

    Active Optical Alignment (AA) precisely positions the lens relative to the image sensor during assembly using real-time optical measurement. Instead of manually adjusting focus, the alignment process actively optimizes the optical path to achieve maximum sharpness and consistency. This method delivers the highest level of focus precision and repeatability, particularly for high-resolution systems and applications with tight optical tolerances.

    • Designed for high-volume production, delivering maximum precision and unit-to-unit consistency
    • Automated, robotic alignment system that actively adjusts focus, tilt, and centering based on live image feedback

THE RIGHT FOCUSING METHOD MAKES THE DIFFERENCE

FRAMOS helps teams choose and implement the optimal focusing strategy, center focusing, multi-region measurement, or active alignment—to achieve reliable image performance.
