Choosing the right lens for imaging applications requires precise calculations of Field of View (FOV), focal length, or object distance. These parameters are essential for machine vision, industrial automation, and security systems, ensuring accurate image capture.
Our FOV Calculator simplifies this process by allowing users to input any two values to compute the third effortlessly.
What Is Field of View (FOV) and Why Does It Matter?
Field of View (FOV) refers to the area a camera can capture at a given distance. Several factors affect FOV:
Focal Length (f): The distance between the lens and the sensor. A shorter focal length increases FOV calculator, while a longer focal length narrows it.
Working Distance (WD): The distance from the lens to the subject. Increasing the working distance expands the FOV.
Sensor Size (S): A larger sensor provides a wider FOV, covering more area.
Selecting the right combination of these factors ensures sharp and distortion-free imaging, which is crucial for object detection, quality control, and surveillance.
How to Use the FOV Calculator
With our FOV Calculator, you can determine an unknown value by entering two known parameters. Follow these simple steps:

Formula for Field of View Calculation
The mathematical relationship between FOV, focal length, and working distance is given by:
fov = SxWD/f
Where:
FOV = Field of View (width or height)
S = Sensor size (width or height)
WD = Working Distance
f = Focal Length
This formula helps determine how much area a camera will cover at a given distance, ensuring the best lens selection for imaging needs.
Choose the Right Lens for Your Imaging System
