Machine Vision Camera Selection Guide

A practical workflow to size a machine vision camera and lens: focal length, FOV, pixel accuracy, placement, depth of field, and bandwidth — with live calculators at each step.

Work the steps in order if you are quoting a new inspection cell. Skip ahead if you already have a lens and only need bandwidth or placement. Every step opens a live calculator — no signup.

1. Step 1 of 6 · Size lens

   Lens Calculator

   Start from the part size and mount height you already know. This gives a focal-length shortlist before you open a catalog.

   Open Lens

2. Step 2 of 6 · FOV specs

   Camera FOV Calculator

   Confirm scene coverage and mm/px for the candidate lens. Back-solve working distance or FOV if the first focal length is too tight.

3. Step 3 of 6 · Resolution

   Pixel Accuracy Calculator

   Check that the smallest defect or measurement spans enough pixels for your algorithm — not just that the part fits in frame.

4. Step 4 of 6 · Cell layout

   Camera Placement Planner

   Move from optics to the cell: mount height, belt offset, and whether the inspection zone sits inside the FOV footprint.

   Open Camera Placement

5. Step 5 of 6 · Focus

   Depth of Field Calculator

   If part height varies or you need stack-up margin, verify near/far focus limits at the aperture you can actually light.

   Open Depth of Field

6. Step 6 of 6 · Bandwidth

   Camera Bandwidth Calculator

   Size GigE, USB3, or CoaXPress from resolution and frame rate so the interface is not the surprise after the camera arrives.
