Choose The Correct Led Coaxial Light Source Solution For You!

Viewing high-reflective objects from flat-surfaces is typically strenuous to accomplish with ring illumination. Light reflects away from the lens whenever it hits the surface, and as a result, a dark image is formed. So, the coaxial illumination is used for viewing the targets and producing a bright picture. This type of lighting usually uses a half-mirror for matching the optical axis of illumination and lens.

As a leading led coaxial light source manufacturer, Nano-optics technology, co ltd is at the forefront of factory automation. We strive and struggle to develop innovative products to meet the needs of our customers in every manufacturing industry. Along with coaxial lights, we also offer a full range of services to assist our customers. Our technically trained and professional team can solve various application issues. We always ensure to provide fast shipping so clients can improve their processes as quickly as possible. Our ultimate priority is to satisfy our customers by adding superior technology with unparalleled support.

Collimated coaxial illumination

Whenever the rays of light are parallel, the light is known to be collimated. Using light from this source is especially useful for detecting flaws and dents on flat and reflective objects. In this case, there is always a perfectly flat surface where objects are seen through the lens.

Advanced coaxial illumination

The usage of an additional reflection chamber isn’t directly emitted from the light source through a semi-transmitter mirror. That plays a crucial role in delivering more homogenous illumination. This type of illumination is ideally suitable for uneven surfaces with a more pronounced profile like wrinkled paper, threads, and screws. The usage of advanced led coaxial light source also provides even illumination with minimal highlights.

Types of coaxial illumination

Proper illumination is the determining factor between the success and failure of illumination. A wide range of products and techniques are developed for overcoming various lighting obstacles. The colors, grooves, deformations, and areas represent the demands according to different applications.

Directional illumination – This is used for focusing and spreading out the illumination. 



– Flexible

– Bright



– Shadowing

– Glare


Glancing illumination: This is similar to directional illumination.


– Shows the structure of the surface

– Enhances the object’s topography


Diffuse illumination – Diffuses the light from an extended source.



– Reduces the intensity of glare

– Provides even illumination.



– Large and difficult to fit in the confined spaces


Bright field/ backlight: This object is lit from behind. That is usually used for opaque and transparent objects.



– High contrast for the detection of edges


– Eliminates the surface details.
