Focal Length/FOV Lens Calculator

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

NOTE: WD and FOV must be in the same units (e.g. in, ft, etc.).

Focal Length/FOV Calculator by Sensor Size


Please select the sensor size.

Please select the horizontal or vertical dimension that you want to calculate

Horizontal Vertical

Enter two of the three values below.

WD:

FOV:

FL:

Focal Length/FOV Calculator by Pixels

Enter number of pixels, pixel size and WD, and FOV or FL.

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 lensFOV - 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!
