Focal Length/FOV Lens Calculator

This calculator is a first order calculator and is very useful for most machine vision applications*.

Enter number of pixels, pixel size and working distance, and either FOV or FL.
NOTE:WD and FOV must be in the same units (e.g. in, ft, etc.).

Number of Pixels: Horizontal Vertical

Pixel Size (µm): Horizontal Vertical

WD:

FOV: Horizontal Vertical

FL: Horizontal Vertical

WD - Working Distance - distance from the front of the lens
FOV - Field of View, width of picture
FL - focal length of the lens

*If your magnification is outside of 0.1 to 10, or ratio of WD/FOV is very high or low (0.05 to 20), or your FOV/Sensor size is very high or low, or you have a very short WD (less than 100mm) , or have any questions, contact us first!
