Coaxial Lights

 

 

Opto-Engineering Coaxial light provide highly diffuse illumination by providing the same optical axis for both the camera and the light source.  This type of light is also commonly known as Diffuse On-Axis Lighting.

The highly diffuse nature of the light field renders this type of illumination ideal for imaging highly specular shiny surfaces. For example, a metal coin can return direct powerful reflections, the most challenging of which is cause by metallic curved surfaces that focus ambient light into a small intense specular highlight. 

LTCXC Series

The LTCXC Series consists of LED coaxial lights that provide coaxial illumination ideal for inspection of scratches/dents on glossy surfaces or pattern inspection on PCB to be used in combination with telecentric lenses.

Light is reflected by a 45° beam splitter so that it is projected on the same axis as the camera. Suggested use is continuous mode.

The use of a beam splitter provides excellent uniformity across the field of view, as the illumination follows the same optical path as the camera lens.
