Vision Calculator
Machine vision math in your pocket.
Pick a camera, sensor and lens, then convert between field of view, working distance and minimum feature size. The app does the optics from the published specifications, so you need little optics knowledge to get answers.

From camera to working distance
Vision Calculator answers the questions that come up when sizing a vision application: will this camera see the whole part, can it resolve the smallest feature, and how far away does it need to be?
Configure a camera
- Swipe through camera models, sensors and lenses.
- Or pick a preconfigured product by its catalog number.
- Extension tubes and custom focal lengths for C-Mount lenses.
Calculate
- Enter any value and the others update instantly: field of view, working distance, pixel size, and minimum cell, bar and character sizes.
- Drag the camera up or down to change the working distance.
- Switch every value between inches and millimeters with one tap.
Find what works
- Store your requirements in memory; each shows green when met and red when not.
- A working range graph marks the distances that meet them.
- The catalog shows which products match your requirements.
Data Matrix mini calculator
- Enter a matrix's rows and width to get its cell size.
- Add white space for positional tolerance to get the field of view it needs.
