The most important facet of any machine vision application is proper lighting — essential to obtaining a proper image.
Creating the perfect contrast and resolution in an imaging system often presents a major challenge that can be readily resolved with proper illumination. Rather than investing in higher resolution detectors, imaging lenses and software to obtain a desired image quality, improving a system's illumination may be the most cost effective solution. Proper light intensity in the final image depends directly upon component selection. Proper illumination is vital to any image system; inadequate illumination creates a variety of imaging problems. Blooming, hot spots, or shadowing can obscure critical image data. Shadowing can result in false edge calculations, resulting in inaccurate measurements. Non-uniform lighting can harm signal-to-noise ratios. A multitude of scenarios of improper illumination for your application can limit your desired imaging result.
Consequently, lighting is the one area of installing a vision system that usually requires some experimentation. It is virtually impossible to predict the exact lighting arrangement that will give the best results for a new application. The main objective of lighting the object is to provide a vision system with a consistent image that clearly shows the features to be inspected.
Our engineers will evaluate your application and guide you through the selection process to provide the optimum combination of components to produce the highest quality image solution.
High-density LED ring lights create an extremely bright concentration of light at the center of the illumination area. Ring lights can be utilized in a wide variety of applications. Unusually bright quantities of light can be obtained due to focused direction onto the object.
Low Angle Ring Lights Low-angle illumination is ideally suited for edge detection and for emphasizing printing, damage, etc. on metal surfaces. Edges and scratches are brought to the forefront by radiating from a low angle.
Bar Lights High intensity LED arrays in rectangular oblique illumination units. The angle of the LED arrays can be adjusted independently for use in a wide range of different situations. Varied radiation is possible depending on the use. Different lengths can be selected as standard illumination to match work. Width and length are changed with custom order requirements.
Dome Lights Dome lights emit even illumination that transmits light at all angles allowing an object to be evenly illuminated. They allow light generation without unevenness and radiate in every direction. A high-intensity type of diffused light; dome lights allow shadowless radiation in applications with fast checking speeds as well.
Coaxial Lights Coaxial lights provide bright, even illumination across the entire field of view. They create an on-axis illumination system that is ideally suited for inspecting mirror-finish objects for scratches, blemishes and other imperfections.
Flat Ring Lights Flat ring lights provide low-power consumption, low-heat generation, long life, and uniformly dispersed flat illumination. They supply evenly diffuse top lighting that eliminates LED glare and shadows for even illumination.
