DCM-SAL coaxial illumination for shadow-free illumination

Description

DCM-SAL coaxial illumination for shadow-free illumination

The diffuse axial illumination allows a very good surface inspection on many surfaces. The light from the axis of the lens illuminates the surface so that shadows and reflections are avoided, for example: To be able to reliably identify surface inscriptions (OCR, OCV). Packaging films become transparent with the illumination type so that underlying surfaces can be inspected.

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

There are different sizes available. The lighting unit should be slightly larger than the component to be inspected.

White and red are the standard light colors. White is ideal for achieving a constant brightness with differently colored articles. White is also usually necessary for use with a color camera.
The monochromatic wavelengths in conjunction with bandpass filters make it possible to eliminate disturbing ambient and daylight within the BV unit. If several cameras and different wavelengths are used with bandpass filters, several measuring channels that work simultaneously can be integrated into one system.

Example:
DCM-SAL0504A-470-S Axial illumination system with 49mm x 40mm illumination area and 470nm flashlight.

There are different flash drivers available. The VST11L has a trigger input and a lamp output, with the VST33I you have access to 3 inputs and outputs. The systems are programmable via a terminal and designed for DIN rail mounting. Alternative are also special Powerful EPI-STROBE drivers available.
