INDUSTRY COMPONENT

Lens

Precision optical lens for machine vision systems that captures and focuses light onto image sensors for industrial inspection and guidance applications.

Component Specifications

Definition
A high-precision optical component designed specifically for industrial machine vision systems, engineered to capture, focus, and transmit light from the target object to the image sensor with minimal distortion. These lenses are optimized for specific wavelengths, working distances, and environmental conditions to ensure accurate image acquisition for quality control, measurement, alignment, and robotic guidance applications in automated manufacturing environments.
Working Principle
Operates on optical refraction principles using precisely ground glass or plastic elements to bend and focus light rays. The lens assembly collects light from the object being inspected, converges it through multiple optical elements to correct aberrations, and projects a sharp, focused image onto the camera's sensor. Advanced designs incorporate anti-reflective coatings, fixed or adjustable apertures, and specialized optical formulas to optimize performance for specific industrial applications.
Materials
Optical glass (BK7, Fused Silica, N-BK7), optical plastics (PMMA, Polycarbonate), anti-reflective coatings (MgF2, multi-layer dielectric), aluminum or stainless steel housing, precision machined brass mounts

Frequently Asked Questions

What is the difference between C-mount and CS-mount lenses?

C-mount lenses have a 17.526mm flange focal distance and 1-inch diameter thread, while CS-mount lenses have a 12.5mm flange distance. C-mount lenses require a 5mm adapter ring for CS-mount cameras, but CS-mount lenses cannot be used on C-mount cameras.

How do I select the right lens for my machine vision application?

Consider these factors: required field of view and working distance (to determine focal length), sensor size (to ensure proper coverage), resolution needs (megapixel rating), lighting conditions (aperture requirements), environmental factors (temperature, vibration, contamination), and mounting compatibility with your camera system.

What maintenance do industrial vision lenses require?

Regular cleaning with appropriate optical cleaning solutions and lint-free wipes, periodic inspection for scratches or coating damage, checking mounting security and alignment, monitoring for condensation in temperature-varying environments, and calibration verification according to manufacturer recommendations.
