Line Generators for Machine Vision Offer Improved Performance

Coherent Inc. (Santa Clara, CA) has introduced a new range of diode-laser based line generators which deliver enhanced flexibility, unique output optimization capabilities, and extended lifetimes. This series of new line generators, called the StingRay, will enable the construction of faster and more accurate machine vision systems that utilize 3D triangulation. The   StingRay series mates a diode laser with high performance electronics and precision, refractive optics for collimation and line generation covering the widest available range of fan angles. They also incorporate optional diffractive elements for creating complex output patterns.  StingRay models are available with output powers as high as 200 mW and at key wavelengths throughout the 450 nm to 1550 nm spectral range, including the popular 450 nm, 520 nm, 635 nm, and 660 nm lines.

StingRay lasers are the first to feature an industry leading, line intensity non-uniformity down to ±5% in a standard product. This high uniformity reduces the need for image post-processing, and translates directly into increased measurement speed and dimensional accuracy. StingRay lasers are also unique in offering external user focusable optics, which allow the laser line to be precisely optimized for the exact distance over which it is projected.  Additionally, the StingRay’s optomechanical design permits “dynamic line balancing,” enabling simple correction of any intensity bias in configurations where the laser must be used at off axis illumination angles. To further enhance usability, Stingray lasers also include an internal “health monitor” that indicates when a diode module is approaching end of life, thus allowing for planned replacement, and avoiding production downtime due to an unexpected failure.

New Laser Cutting Machine Offers Faster Throughput and Higher Accuracy

 Coherent, Inc. (Santa Clara, CA) has extended its integrated laser tools product portfolio with its new META platform, offering improved performance and greater ease-of-use.  The META platform features a unibody chassis design. This rigid single weldment provides improved mechanical stability for the system, resulting in faster cutting speeds and better positioning repeatability. In addition, the cutting bed on META platform products has been enlarged to accommodate standard European sheet sizes (1.25 m x 1.25 m).

The control system has also been significantly upgraded with the help of our science laserresearchers. Specifically, the operator interface for META platform products has been changed to an industrial type controller. This is an ergonomic monitor/keyboard assembly that is directly mounted on the side of the chassis.  All interface cables for this system are now contained within the machine assembly, further enhancing its ruggedness and suitability for the increasingly industrial environments in which the platform is now being utilized.

Improvements have also been implemented in the META platform’s software. In particular, ease-of-use has been enhanced through a new, multilingual software interface, together with the implementation of greater system automation. Additionally, the system features automatic focus, advanced capacitive height sensing and a fully integrated machine vision system.

When configured with a Coherent 1 kW CO2 laser (Diamond E-1000), the META system offers unmatched flexibility, with the ability to process a wide range of both metals and non-metals, such as plastics, wood, fabrics, leather, paper and thin films. With this laser cutter tool, the system can readily cut stainless steel in thicknesses of up to 3mm, aluminum of up to 2 mm, and mild steel of up to 6 mm.
