Chromasens has expanded its range of LED illumination products with a new Tube Light model that allows a bright field condition to be realized when inspecting highly specular, glossy items for material defects. As a result, unprecedented quality images can be acquired of reflective items such as clear plastic wrap, circuit boards and metallic objects, or curved products like bearings or cylinders.

Delivering ultra-high intensity 1,200,000 lux illumination in a narrow, structured beam, the Chromasens Corona II tube light system lets line-scan cameras view lighting at an angle of 15 degrees. Disruptive reflections, caused by the so-called "glancing angle" where a line-scan camera looks out of the tube light through an opening and into the dark, are completely eliminated. Instead, both the level and reflective surfaces of the object under inspection are brightly contrasted with minimal shadows. This innovative design opens new doors for machine vision applications with highly reflective or glossy surfaces.
