Why Low Distortion Matters for Industrial Cameras

Q1: What is the difference between C-mount and CS-mount lenses?
C-mount has a 17.526mm flange distance, while CS-mount is 12.52mm. C-mount lenses can adapt to CS-mount cameras with a spacer ring, but CS-mount lenses cannot be used on C-mount cameras.
Q2: Are high MP C-mount lenses necessary for industrial use?
Not always. Match the lens resolution to your camera sensor. Excessively high pixels will increase cost, while insufficient resolution will cause blurry details.
Q3: Can TOWIN provide custom C-mount industrial lenses?
Yes. TOWIN supports personalized focal length, coating, structural size and logo customization to meet unique machine vision project demands.
Q4: Do industrial C-mount lenses need waterproof performance?
It depends on the working environment. For factory dust-proof and humid scenes, you can choose our sealed and dustproof upgraded C-mount lens models.
