35mm C-Mount Industrial Lens Applications

Core Application Scenes

Precision Dimensional Inspection
The <0.05% TV distortion specification makes this lens suitable for dimensional inspection where image geometry needs to remain highly consistent across the field of view. Typical targets can include machined components, molded parts, metal components, connectors, and other manufactured products.

Factory Automation and FA Systems
The combination of 35mm focal length, 5MP resolution, manual aperture, and C-Mount compatibility makes this lens suitable for integration into automated inspection stations. It can be used with industrial cameras mounted above conveyors, inspection fixtures, robotic workcells, and production-line equipment.

Machine Vision Measurement
Low optical distortion can reduce geometric errors introduced by the lens during image-based measurement. This is useful for applications involving part dimensions, component positioning, edge detection, hole inspection, alignment, and profile analysis.

Component and Surface Inspection
The controlled field of view provided by the 35mm focal length can help isolate a target area while maintaining detailed image information. The manual focus and aperture controls also allow engineers to optimize the optical setup during system installation.
