Machine Vision Lighting Types

Understanding unique machine vision illumination methods in line telecentric and diffuse axial lighting techniques each offer distinct advantages for disparate applications.

Machine vision lighting types.

Fluorescent quartz halogen and led are by far the most widely used lighting types in machine vision particularly for small to medium scale inspection stations whereas metal halide and xenon are more typically used in large scale applications or in areas requiring a very bright source. Direct incident light diffuse incident lighting lateral light at angles illumination at a shallow angle from all sides. 3d optics aoi application notes. In line or coaxial illumination figure 1 incorporates a light source such as a fiber optic light guide or led source directly into the optical train of an imaging lens system often using a beamsplitter.

We supply a broad range of solutions in light lenses and cameras. This article covers the advantages disadvantages and use cases for several unique machine vision illumination methods such as in line telecentric and diffuse axial illumination. Not the object itself but only the visual image of the object is checked. Our innovative products enable reliable inspections in many applications thanks to their flexibility robustness and ease of use.

Lots lighting tech specialist is a leading organization in developing and manufacturing machine vision lights for the advanced lighting industry. It follows that only homogeneous lighting conditions result in a consistent image of the same inspection object. This integrated light reduces shadowing and provides uniform illumination on matte objects. The in sight integrated light is a diffuse ring light that provides bright uniform lighting on the target for machine vision applications.

The lighting sources now commonly used in machine vision are fluorescent quartz halogen led metal halide mercury and xenon. Lighting for industrial machine vision lighting plays a major role for industrial machine vision. Dark field transmitted light backlit image.
