In the fast-paced realm of machine vision, precision is non-negotiable. Whether it’s quality control in manufacturing, robotic guidance, or 3D metrology, the margin for error is infinitesimal. Enter M12 telecentric lenses for machine vision—a revolutionary optical solution designed to eliminate perspective errors and deliver unmatched accuracy. TOWIN, a leading optical lenses supplier based in China, specializes in crafting these lenses to meet the rigorous demands of industrial automation.

What Are M12 Telecentric Lenses for Machine Vision?

M12 telecentric lenses are a subset of telecentric optics engineered specifically for machine vision systems. Unlike conventional lenses, which suffer from parallax errors (where object distance affects perceived size), telecentric lenses maintain constant magnification across the entire field of view. This means measurements remain accurate regardless of an object’s position relative to the lens—a critical feature for applications like dimensional inspection or defect detection.

The “M12” designation refers to the lens’s S-mount thread (M12x0.5), allowing direct integration with PCB cameras, also known as “board lenses.” Their compact size and lightweight design make them ideal for space-constrained setups, while their telecentricity ensures reliability in high-speed, high-throughput environments.

Key Product Parameters of TOWIN’s M12 Telecentric Lenses

TOWIN’s M12 telecentric lenses are built to excel in industrial settings. Here’s a breakdown of their technical specifications:

Magnification Range:

• TOWIN offers fixed magnification options (e.g., 0.1x, 0.3x, 0.5x) tailored to specific applications. Lower magnifications suit wide-area inspections, while higher magnifications focus on fine-detail analysis.

Aperture & F-Number:

• The lenses feature adjustable apertures (e.g., F/8 to F/22) to control light intake, ensuring optimal exposure even in varying lighting conditions. This flexibility is vital for outdoor or unevenly lit environments.

Working Distance:

• TOWIN’s lenses provide working distances from 20mm to 200mm, accommodating objects of different sizes. Shorter distances are perfect for close-up inspections, while longer ranges suit large-scale assemblies.

Depth of Field:

• With depth of fields up to 10mm, these lenses maintain sharp focus across uneven surfaces, reducing the need for precise object positioning.

Resolution & Distortion:

• TOWIN prioritizes ultra-low distortion (<0.1%) and high resolution (up to 5 megapixels), ensuring crisp images free from geometric aberrations. This is critical for applications like semiconductor wafer inspection.

Coating Technology:

• Multi-layer anti-reflective coatings minimize flare and ghosting, enhancing contrast and clarity. For night-vision compatibility, TOWIN offers IR-corrected variants.
