Machine Vision Lens Fundamentals to Consider

  • There Are Three Basic Principles Of Lens Selection:

    • Lens Object FOV is a little larger than customer required FOV.

    • Lens Image FOV is equal or larger than camera sensor size.

    • Mag below 1X refers to low mag, above 1X refers to high mag.


  • There Are 3 Important Factors That Contribute In The Selection Process:

    • Image FOV, the sensor size of camera

    • Object FOV, the size of observed object

    • Working Distance

    By image FOV and object FOV, the magnification of the lens can be acquired, that is image FOV/Object FOV.

    Knowing the above, we can select a suitable lens from the existing product list.


  • Example:

    Camera:1/2.5’-5MP

    Sensor size: 5.7*4.3mm

    FOV: 60*40mm

    To pick a suitable lens, first to calculate the mag, 5.7/60=0.095X, 4.3/40=0.1075X.

    Lower mag will be picked so as to cover full FOV.

    From Canrill product line, Canrill fouth generation PTL series PTL-08 series is the most suiable, and the mag of XF-PTL09228 is 0.0847, is the closest figure to 0.095X.

    Thus XF-PTL09228 is selected.
