What Is a C-Mount Machine Vision Lenses?

C-mount machine vision lenses are complete optical assemblies designed for industrial imaging applications. They feature a standard C-mount thread (1"-32 TPI) for compatibility with C-mount and CS-mount cameras.

These lenses are optimized for high resolution, low distortion, and telecentric or near-telecentric performance, making them ideal for precision measurement, inspection, and automated quality control in manufacturing environments.

When Should You Use This Product?

✔ Good Choice When

✓ Industrial inspection and quality control systems
✓ Barcode and OCR reading applications
✓ Precision measurement with low distortion
✓ Automated manufacturing line vision systems

⚠ Consider an Alternative When

✗ Custom optical design needed → Plano-Convex + custom assembly

✗ Microscope-level magnification → Microscope Objective

✗ Large-area coverage → Larger format lens

✗ UV imaging → UV optics assembly

Optical Coating Options

Multi-Layer BBAR

Broadband AR across visible spectrum. R < 0.5% per surface.

Typical use: All machine vision applications

Enhanced Contrast

Special coatings to reduce ghosting and flare.

Typical use: High-contrast inspection applications

How to Specify Your Coating

To select the right coating, please provide: (1) Operating wavelength, (2) Angle of incidence, (3) Required transmission or reflectivity, (4) Laser power density (if applicable), (5) Operating environment.

Engineering Considerations

Key factors to evaluate when specifying this optical component for your system.

Sensor Matching

Match lens image circle to sensor size. 2/3" lens on 1/3" sensor works; reverse causes vignetting.

Working Distance

Determine required WD and depth of field. Shorter focal length = wider FOV at same WD.

Distortion

For metrology applications, specify low distortion (< 0.1%) or apply software correction.

Resolution

Match lens resolution (line pairs/mm) to pixel pitch of your camera sensor.

C-Mount vs CS-Mount

C-mount = 17.526mm flange distance. CS-mount = 12.526mm. Use C-to-CS adapter ring if needed.

Frequently Asked Questions

What materials are available for this lens type?

We offer multiple substrate materials including N-BK7, UV Fused Silica, CaF₂, and Sapphire depending on your wavelength and environmental requirements.

Can I order custom specifications?

Yes. PhotonEdge offers custom diameters, focal lengths, coatings, and surface qualities. Custom specifications typically require 4-6 weeks lead time.

What surface quality should I specify?

40-20 is suitable for most laser and imaging applications. 20-10 is recommended for precision systems where scattering must be minimized.

What coating do I need?

The coating depends on your operating wavelength. For visible applications, AR 350-650nm is standard. For NIR lasers, choose the coating matching your wavelength. Uncoated is suitable for non-critical applications.

Do you provide inspection reports?

Yes. Dimensional reports, surface quality verification, and coating performance data are available according to project requirements.
