Designing a machine vision system starts with making sure you have enough light for a clear image—especially for fast-moving targets and short exposures. LED lights are rated in lumens, but cameras detect photons, not brightness seen by the human eye. To bridge that gap, Bodkin Design developed a Lumen-to-Photon Calculator Spreadsheet that converts LED lumen ratings into spectral photon flux matched to your camera’s quantum efficiency. This lets you accurately estimate exposure, well-fill, and signal-to-noise for your own imaging setup.
