C and CS Mount Lenses for Industrial, Scientific, and Security Vision Systems

Delivering the Right C or CS Lens for Your Sensor, System, and Space

C and CS mount lenses remain industry standards for machine vision, quality control, scientific imaging, and high-performance security systems. The key difference lies in flange focal distance—C mount lenses offer a longer 17.526mm spec, while CS mount lenses use a more compact 12.526mm back focus. With the right adapter or design choices, both formats offer flexibility in optical system design.

FRAMOS helps you evaluate sensor alignment, focal requirements, back focus constraints, and housing mechanics to ensure that your selected lens fits and performs exactly as needed. We also assist in determining whether a C or CS mount makes more sense for your application, offering adapter support and dimensional consultation as needed.
