Collection: C-Mount Lenses

Q: What are C-Mount lenses?

A: The C-Mount is a 1-inch thread with a pitch of 32TPI.

Q: What is the difference between C-Mount lenses and other types of lenses?

A: This depends on what other type of lens you are comparing it to. See our blog on the different types of lens mounts.

Q: What are the benefits of using C-Mount lenses in machine vision applications?

A: When compared to an equivalent M-12: Improved performance*. Focus is more stable due to locking rings not being required. Adjustable f/stop. Adjustable focus.

Q: What are the downsides of using C-Mount lenses in machine vision applications?

A: If space is a limiting factor, a C-mount lens could be too large. If cost is an issue, M12 might be a better option.

Q: How do I choose the right C-Mount lens for my application?

A: Speak to us at Scorpion Vision if you're unsure of any technical specifications or performance parameters.

Q: Are there any limitations to using C-Mount lenses in machine vision applications?

A: C-mount lenses are generally designed for image sensors with a format of 4/3" or smaller. If you have a larger sensor or a long line scan camera, you may experience vignetting. Speak to us if you have any concerns about this.

Q: What are some common applications for C-Mount lenses?

A: Virtually any machine vision application you can think of.

Q: Do C-Mount lenses have distortion?

A: Every lens has a level of distortion. However, quality machine vision lenses from Scorpion Vision have a lower level of distortion than other competitive products. It should also be noted that the shorter the focal length, the greater the level of distortion.

Q: Do C-Mount lenses exhibit chromatic aberration?

A: Quality C-Mount lenses should not show chromatic aberration - which can be seen as fringes of colour in the image where the contrast between dark and light is present.
