C-Mount Lenses are standardized optical lens assemblies featuring a 1-inch (25.4 mm) diameter threaded mount with a 17.526 mm flange focal distance, engineered to focus reflected light precisely onto machine vision camera sensors. Built to deliver high optical resolution, low geometric distortion, and high contrast, these industrial lenses maintain sharp image clarity across full sensor areas for precise inspection and measurement tasks. Key hardware features typically include high-grade anti-reflective glass elements, manual or lockable focus and iris rings, rugged metal barrels, filter threads, and vibration-resistant locking screws.
