Machine Vision Coaxial Light: Precision Inspection Solution for Global Manufacturers

Machine Vision Coaxial Light: Precision Illumination for Global Quality Control

In high-speed production lines across Europe, Southeast Asia, and the Middle East, manufacturers face the challenge of detecting microscopic defects on reflective surfaces like PCBs, glass, and polished metals. Traditional ring lights create glare and shadows that obscure critical details, leading to costly false rejects and rework. Our Machine Vision Coaxial Light delivers uniform, glare-free coaxial illumination that reveals surface scratches, solder joint defects, and alignment errors with exceptional clarity, reducing inspection errors by up to 40%.

How to Choose the Right Machine Vision Coaxial Light for Your Application

Selecting the correct coaxial light depends on your target material, inspection speed, and working distance. Below we compare our standard model with traditional lighting solutions to help you make an informed decision.

IP Rating	IP67 (dust and water resistant)	IP40 typical
Lifetime (MTBF)	60,000 hours	25,000 hours
Warranty	3 years	1 year

Production Process: From Design to Delivery

Our manufacturing follows a strict six-step process to ensure every Machine Vision Coaxial Light meets international quality standards.

Production flow for Machine Vision Coaxial Light: six stages from optical design to final quality inspection

1. Optical Design: Engineers use Zemax simulation to optimize light path and uniformity for specific customer applications.
2. Component Sourcing: We source high-CRI LEDs from certified suppliers (Osram, Cree) and optical-grade beam splitters from Germany.
3. Precision Assembly: All components are assembled in a Class 10,000 cleanroom to prevent dust contamination.
4. Calibration: Each unit is calibrated using a spectrometer and goniometer to ensure consistent color temperature and intensity.
5. Environmental Testing: Lights undergo 48-hour burn-in at 50°C and 95% humidity to verify reliability.
6. Final Quality Inspection: 100% functional test with a reference target to confirm uniformity and output power.

Quality Control System: Certifications and Testing

We maintain multiple certifications to guarantee product reliability for global customers:

• ISO 9001:2015 certified quality management system for design and manufacturing.
• CE and RoHS compliance for European markets.
• REACH and WEEE compliance for environmental safety.

Frequently Asked Questions

What is the difference between a coaxial light and a diffuse light?

Coaxial light uses a beam splitter to direct light parallel to the camera lens, creating a bright-field effect ideal for detecting surface scratches and dents on reflective surfaces. Diffuse light uses multiple angles to eliminate shadows, better for matte surfaces.

Can I use this light with any brand of camera?

Yes, our coaxial lights are designed with standard C-mount or CS-mount threads and are compatible with all major machine vision cameras from Basler, FLIR, Cognex, Keyence, and others. An adapter ring is included.

How do I clean the optical window?

Use a lint-free cloth with isopropyl alcohol (70% concentration). Avoid abrasive cleaners. The front window is coated with anti-reflective material and can withstand up to 100 cleaning cycles.
