CMS Laser is a Cognex-Certified Vision Integrator. Our Vision Lab includes various Dataman and Insight cameras, as well as a full range of lenses and diode lights in different wavelengths. We combine this hardware with our extensive knowledge of Cognex software and vision algorithms to develop off-axis, robot and coaxial vision systems.
Our engineers have been developing and integrating vision systems into laser machines for more than two decades. We leverage this expertise to design the perfect laser system for your application—taking into account the following:
Cameras. We work with a variety of cameras and determine the best fit based on resolution, process speeds, available algorithms—and more. High-resolution cameras (greater than 1 megapixel) are ideal for processing finer details and tight tolerances within a larger field of view. Low-resolution cameras (less than 1 megapixel) require less processing time and computing power. They’re ideal when speed or cost take priority over accuracy.
Lighting. We can program a vision system’s lighting functions to have multiple configurations within the same system. We account for bright and dark fields, diffuse versus direct lighting, backlighting, colors—and more.
Optics. We can set up our cameras in different ways depending on your application. Common configurations include:
- Off-axis direct view. The camera and laser point downward as the laser performs its function. This setup works well for conveyors.
- Off-axis at an angle. While the laser points downward, the camera sits off to the side and at an angle—eliminating the need for motion between the laser and camera position. Due to the angle, the software corrects the distorted image using perspective calibration.
- On-axis, or through the optics vision. We set up the camera system within the same lens as the laser. Though the field of view is small, this configuration is extremely fast and provides both high resolution and magnification.
