Overview of The Imaging Source's Lenses for Industrial Imaging
Lenses
C/CS Mount
High-performance internal-focus lens with variable aperture
The Imaging Source's housed industrial cameras ship with either C- or CS-mounts, and we offer a broad range of suitable lenses-from high-end C-mount lenses to inexpensive CS-mount lenses.
Cost-optimized vision solutions can be realized with cameras using a small sensor and CS-mount lenses. These affordable lenses have a shorter flange focal distance, allowing for a smaller footprint. At the same time, the aperture of a CS-mount lens can be adjusted, increasing overall system flexibility.
For vision applications requiring high-performance imaging, we recommend C-mount lenses. These industrial camera lenses typically consist of more optical elements-optimally resolving the newer, larger sensors with improved correction of common lens aberrations.

Board Lenses
M12 (S-Mount)
Robust fixed-focus lenses with external focus adjustment
Compact and lightweight M12 lenses are typically used in conjunction with board cameras. The M12 lenses' fixed aperture makes them more resistant to mechanical stresses such as vibrations or shocks.
Due to their smaller optical components and simpler focusing system, M12 lenses are also generally less expensive than C/CS-mount lenses. When used with CS-mount cameras, M12 lenses can also provide super wide-angle FOVs.
The board-camera and M12 lens combination delivers one of the lightest and most compact industrial imaging solutions possible.

Extension Tubes
C-Mount Extension Tubes and Spacer Rings
For applications with short working distances / higher magnification requirements
In addition to The Imaging Source's broad portfolio of lenses, we also offer extension tubes and spacer rings to allow for maximum system flexibility. Extension rings and spacers are especially useful when imaging an object field that is closer to the camera than allowed by the minimum focus distance (MOD) of the lens.

Optimal contrast for image processing reproducibility and stability.
The primary task of any vision system's hardware is the production of high-contrast images, allowing for relevant image data extraction and reduced processing time. Optical filters for machine vision applications deliver significant improvements to image contrast. Bandpass filters, for example, greatly improve contrast in monochrome images while polarization filters reduce glare and surface reflections.
We are happy to help you with the selection of optical filters suitable for your machine vision application.
