High-Performance Linear Coaxial Light Solutions for Global Buyers: A Complete Procurement Guide

In automated visual inspection systems across Southeast Asia, the Middle East, and Europe, inconsistent lighting remains the primary cause of false rejects and missed defects. The linear coaxial light eliminates shadowing and glare on reflective surfaces such as PCB solder joints, medical device components, and automotive glass. Our engineered solution delivers uniform illumination at a 45-degree angle, enabling detection of scratches, dents, and contamination that traditional ring lights simply cannot catch.

Why Your Vision System Needs a Linear Coaxial Light

Standard LED bar lights create hotspots and uneven brightness when inspecting shiny or curved objects. A linear coaxial light uses a beamsplitter to project light along the same optical axis as the camera, making surface defects appear as high-contrast features. This technology is essential for quality control in electronics manufacturing, pharmaceutical packaging, and metal finishing industries.

How Is a Linear Coaxial Light Manufactured? Step-by-Step Process

Linear coaxial light manufacturing workflow: from SMD LED selection to final 100% optical performance testing.

1. LED Die Bonding & Wire Bonding: High-CRI LEDs are mounted on aluminum-core PCBs using silver epoxy for optimal thermal transfer.
2. Beam Splitter Assembly: Precision-polished glass with 50/50 reflective coating is aligned within 0.1mm tolerance.
3. Optical Alignment Station: Each unit undergoes automated laser alignment to ensure collimated output.
4. Thermal Cycling Chamber: 100 cycles from -20°C to +70°C to verify solder joint reliability.
5. Final Performance Test: Uniformity, color temperature, and intensity are measured against NIST-traceable standards.

Quality Control and Certification Standards

Every linear coaxial light ships with a traceable QC certificate. Our facility is ISO 9001:2015 certified for quality management systems. We also hold DNV and BV type-approval for marine and offshore applications. Routine testing includes:

• ESD sensitivity testing per ANSI/ESD S20.20
• Salt spray corrosion testing per ASTM B117 (48 hours)
• Vibration resistance per IEC 60068-2-6 (10-500Hz, 2g)

Frequently Asked Questions: How to Select the Right Linear Coaxial Light

Q: What working distance should I choose?

For most machine vision applications, a 50-100mm working distance gives optimal contrast. Our sales engineers can recommend the exact standoff based on your camera lens and field of view.

Q: Can I get a custom length?

Yes. We offer custom lengths from 50mm to 2000mm in 10mm increments. Custom beam splitter coatings are available for UV or NIR wavelengths.

Q: How do I communicate with your team across time zones?

Our technical support desk operates 24/5 via WhatsApp and WeChat. For urgent issues, we provide a local agent in Germany, UAE, and Singapore.

Q: What documentation do I need for customs clearance?

We provide a commercial invoice, packing list, certificate of origin (Form A or CO), and a free-sale certificate for medical devices. A bill of lading is issued within 48 hours of shipment.

Customer Success Stories

"We replaced 12 bar lights with 6 linear coaxial lights from OptiVision. Our defect detection rate improved from 92% to 99.7% on aluminum heat sink inspection. The 3-year warranty gave us confidence to make the switch."
