7、diffuse on-axis lighting for surface inspection

Diffuse on-axis lighting (DOAL) is a specialized technique used for inspecting highly reflective or specular surfaces such as mirrors, polished metal, and glass. This method combines a beam splitter and a diffuse light source to illuminate the object from the same optical path as the camera, effectively eliminating glare and revealing surface defects like scratches, pits, and stains. The light is first diffused through a specialized plate or integrating sphere, then directed through a semi-reflective mirror onto the object. The camera captures the reflected light, which carries information about surface topography without the harsh reflections typical of direct lighting. DOAL is particularly effective for inspecting semiconductor wafers, optical lenses, and automotive trim. Manufacturers of diffuse on-axis lighting systems focus on achieving high uniformity across the entire field of view, often using custom-designed diffusers that scatter light evenly. The beam splitter must have precise coatings to balance transmission and reflection ratios, typically 50:50 or 70:30 depending on the application. Working distances for DOAL systems are generally short, from 20mm to 150mm, to maintain light intensity. Thermal management is important to prevent heat from affecting the beam splitter or diffuser performance. Many DOAL lights include adjustable intensity controls and interchangeable diffusers for different surface characteristics. The main advantage of this lighting method is its ability to highlight subtle defects that would be invisible under standard ring or bar lighting. However, it requires careful calibration and alignment to achieve optimal results. Leading manufacturers offer DOAL as both standalone units and integrated modules for existing vision systems. For quality control teams dealing with shiny objects, diffuse on-axis lighting is often the only reliable solution for achieving consistent, repeatable inspections.
