• LED illuminators

Illumination is a critical part of every machine vision setup: proper choice of lighting color and geometry can effectively suppress or reveal specific features of an object, leading to simple and accurate image processing.
 
Opto Engineering offers a wide range of illumination solutions including ring lights, dome illuminators and a unique space-saving lighting system complemented by specific high power/strobe controllers. The Opto Engineering illuminators family provides innovative and robust lighting units, designed to deal with fast-moving objects of various sizes and surface finishes, such as highly reflective or curved samples.

• LED pattern projectors

Opto Engineering LED pattern projectors have been designed for 3D profiling/reconstruction and for the measurement of objects with complex structures or inclined planes. They are successfully used in a variety of applications like quality control in food and packaging to check for correct volume, reverse engineering, dimensional measurement of electronic components, planarity control of products, robot guidance for pick and place and alignment applications. When compared to laser emitters, LED technology ensures more homogeneous illumination in addition to sharp edges and no speckle effect.
 
Many 3D machine vision applications require structured light to be projected onto inclined surfaces, i.e. at a certain angle from the vertical axis. In such cases, the focus is maintained only within a small area close to the centre of the field of view and the rest of the image shows relevant defocusing, thus making 3D measurement inaccurate.

For this reason, our family of pattern projectors includes special projectors equipped with a highprecision tilting mechanism that allows the pattern of the light source to meet the Scheimpflug condition so that the projected light is properly and evenly focused across the entire sample surface. All Opto Engineering LED projectors feature a wide selection of interchangeable patterns. Furthermore, the size of the projection area can be easily modified by interchanging different 2/3’’ C-mount lenses. To achieve the best results we suggest to use bi-telecentric lenses or zero distortion macro lenses.
