Description

DCM-SAR - Coaxial illumination with independent ring light for shadow-free illumination and Emphasizing surface defects.

The diffuse axial illumination allows a very good surface inspection on many surfaces. The light from the axis of the lens illuminates the surface, avoiding shadows and reflections For example, to be able to reliably recognize surface labels (OCR, OCV). Packaging films are used with the type of lighting transparent so that underlying surfaces can be inspected.

Due to the additional diffuse Ring lighting, which can be controlled independently of the coaxial element, causes irregularities or defects in the surface highlighted.

Due to the 90 ° arrangement, the height of the image processing chain can be significantly reduced.

The lighting unit should be slightly larger than the component to be inspected.

White and red are the standard light colors. White is perfect for different colored articles to achieve a constant brightness. White is also common for use with a color camera necessary.
The monochromatic wavelengths in conjunction with bandpass filters allow the elimination of disturbing ambient and daylight within the BV unit. When using multiple cameras and different Wavelengths with bandpass filters allow multiple measurement channels that work simultaneously to be integrated into one system.

Available wavelengths
