Diffuse On Axis Light™--DOAL¨

With the DOAL, light rays reflect off the beam splitter directly on to the object at nearly 90°. With this approach, specular surfaces perpendicular to the camera appear illuminated, while surfaces at an angle to the camera appear dark. Non-specular surfaces absorb light and appear dark.

Collimated On Axis Light--COAL

COAL modules provides collimated illumination in the same optical path as the camera. The COAL is designed for applications requiring co-axial bright light.

For Flat Specular Surfaces

DOALs provide diffuse, uniform illumination for flat specular surfaces. By providing greater uniformity than conventional sources, DOALs increase machine vision accuracy and repeatability up to 200%.
