Industrial lenses are the backbone of modern automation, surveillance, and machine vision systems. From robotics to traffic monitoring, these specialized optics ensure clarity, accuracy, and reliability in demanding environments. But with countless variations on the market, how do professionals classify and select the right industrial lens for their needs?

The 5 Main Classifications of Industrial Lenses

Industrial lenses are categorized based on their mount type, optical design, and intended application. Below, we explore the most common types, their technical specifications, and real-world uses.

1. S-Mount Lenses: Compact Powerhouses for Embedded Vision

M12 lenses, also known as S-Mount or board lenses, feature a standard M12X0.5 thread that screws directly into PCB cameras. Their compact size (often under 10mm in diameter) makes them ideal for embedded systems where space is limited.

Key Parameters:

• Focal Length: 1.8mm to 12mm (wide-angle to telephoto)
• Distortion: Low distortion models available for precise imaging
• Aperture: Fixed or adjustable (e.g., F/2.0 for low-light sensitivity)
• Applications: Drones, medical devices, IoT cameras, and automotive ADAS systems.

TOWIN’s Offerings:

TOWIN provides a range of M12 lenses, including fisheye, wide-angle, and pinhole variants. Their low-light sensitive lenses excel in dim environments, while automotive-grade optics meet stringent safety standards.

2. C-Mount Lenses: The Workhorses of Machine Vision

C-Mount lenses have a flange focal distance of 17.526mm, making them compatible with industrial cameras used in factory automation, 3D scanning, and quality control.

Key Parameters:

• Resolution: Megapixel-rated for high-detail imaging
• Iris Control: Manual, DC Auto, or P-Iris for dynamic lighting
• Zoom Capability: Fixed or vari-focal lenses for flexible framing
• Applications: Robotics, semiconductor inspection, and packaging systems.

TOWIN’s Offerings:

TOWIN’s C-Mount lenses include high-resolution models with IR correction for day/night surveillance. Their traffic monitoring lenses (ITS lenses) are engineered for high-speed vehicle recognition.

3. CS-Mount Lenses: Cost-Effective Surveillance Solutions

CS-Mount lenses, with a shorter flange distance (12.526mm), are designed for CCTV, network, and IP cameras. They are lighter and more affordable than C-Mount alternatives.

Key Parameters:

• Focal Range: Fixed or vari-focal (e.g., 2.8mm–12mm)
• Coating: Multi-layer anti-reflective coatings for clarity
• Night Vision: IR-corrected for 24/7 operation
• Applications: Smart cities, retail analytics, and perimeter security.

TOWIN’s Offerings:

TOWIN’s CS-Mount lineup features megapixel lenses with low distortion and P-Iris technology for optimal exposure. Their vari-focal lenses simplify installation in variable environments.

4. Fisheye & Wide-Angle Lenses: Panoramic Vision Unleashed

Fisheye lenses (180°–220° field of view) and wide-angle lenses (60°–120°) are essential for capturing expansive scenes in a single shot.

Key Parameters:

• Distortion: Corrected or intentional (for immersive effects)
• Depth of Field: Deep focus for close-up and distant objects
• Applications: Virtual reality, surveillance domes, and panoramic photography.

TOWIN’s Offerings:

TOWIN’s fisheye lenses offer ultra-low distortion, while their wide-angle models balance clarity and coverage.

5. Specialty Lenses: Tailored for Niche Demands

• Beyond standard classifications, specialty lenses address unique challenges:
• Telecentric Lenses: For metrology and dimensional measurement
• Macro Lenses: High magnification for small-object inspection
• Polarizing Lenses: Reduce glare in industrial settings

TOWIN’s Innovations:

TOWIN develops custom optics for automotive lidar, agricultural drones, and AR/VR headsets.
