Coaxial Light is essential in machine vision lighting systems, delivering uniform illumination for reflective and flat surfaces. It directs light along the same optical axis as the camera, effectively eliminating shadows and glare. At KCS (Guangdong Shunshangxin Photoelectric Technology Co., Ltd.), we combine in-house R&D with advanced production to provide reliable coaxial illumination solutions for automated inspection environments.
Our Coaxial Light for Inspection products meet the demanding requirements of precision imaging and complement our full range of machine vision lighting solutions for industrial automation.
KCS Coaxial Lights provide high uniformity and stable illumination, ensuring clear imaging even on highly reflective materials. These LED-based lights feature a compact structure, long service life, and excellent reflection control. Key benefits include:

| Standard LED Coaxial Light | Balanced illumination for general use | Flat surface and reflective object imaging |
All models are available in multiple wavelengths and housing materials to suit specific inspection needs.
Coaxial Lighting is widely used in machine vision systems that require shadow-free imaging of reflective or smooth surfaces. Common applications include:
PCB and semiconductor inspection
Glass and display defect detection
Metal surface and precision component inspection
Marking and engraving verification
By integrating our coaxial illumination with high-resolution cameras and lenses, KCS enhances image clarity and consistency across diverse inspection tasks.
Choosing the right Coaxial Light depends on surface reflectivity, inspection area, and camera configuration. The table below provides a quick selection guide:
| Selection Factor | Recommendation |
|---|---|
| Inspection Surface | Use high-brightness coaxial lighting for low-reflectivity materials |
| Working Distance | Match light size and beam angle with the camera’s field of view |
| Color/Wavelength | Select wavelength based on material color and contrast requirements |
| Brightness Control | Pair with KCS light source controllers for adjustable intensity |
For advanced control and synchronization, we recommend integrating the coaxial light with our dedicated light source controllers for precise brightness and timing adjustment.

Q1: What is a coaxial light used for in machine vision?
A1: Coaxial lights provide uniform illumination for reflective or flat surfaces, enabling clear and consistent imaging in inspection systems.
Q2: How does a coaxial light differ from a ring light?
A2: A coaxial light directs illumination through a beam splitter for even lighting, while a ring light projects light around the lens at an angle.
Q3: Can KCS customize coaxial lights for specific applications?
A3: Yes, we offer customization for size, wavelength, and brightness to meet specialized inspection requirements.
Q4: What industries commonly use coaxial lights?
A4: Coaxial lights are widely used in electronics, semiconductor, glass, and metal inspection industries.
Q5: How do I control the brightness of a coaxial light?
A5: Our coaxial lights can be paired with KCS light source controllers for precise brightness and timing control, ensuring optimal performance during inspection.
