You can depend on our advanced equipment and experienced team to meet your needs for quality control, from executing against demanding industry specs to designing your optimal quality control strategy.
Parts micromachined by lasers often have features too small to be seen by the naked eye. Laser Light Technologies has a system to ensure optimal inspections and quality. We provide highly trained staff with your particular quality specs and the ideal tools for performing visual inspections: high-powered microscopes and specialized instruments for micro-measurement of linear dimensions, height, depth and 3D profile.
Our four Coordinate-Measuring Machine (CMM) systems, also known as vision machines, use video to identify micro-level flaws with impressive speed and efficiency. Laser Light Technologies utilizes these automated optical inspection systems for testing and measurement of high-volume parts production, ensuring we meet your unique Geometric Dimensioning and Tolerancing (GD&T) specifications.
Our Confocal Laser Scanning Microscope systems utilize a wide range of individual objective lenses and laser scanning to rapidly generate a 3D profile of any part, for the highest accuracy in both shape and surface data. These systems are ideal for intensive R&D evaluations. They combine the ability to generate high-resolution optical images with comprehensive software that includes GD&T reporting features.
As a Laser Light Technologies customer, you have access to a variety of reports and methods to help you keep an eye on quality control, including:
As the top U.S. consumer of excimer lasers with more than 30 years’ working experience, Laser Light Technologies has well established expertise.
The excimer laser’s advantage is large, exacting bursts of light that are unrivaled in size by any other laser. This gives them the ability to cover large areas while maintaining micron-level accuracy. When combined with our cutting-edge motion and optical components, they deliver high-volume throughput. This makes excimer lasers the most cost-effective option for many micromanufacturing needs.
This laser type’s established technology excels at processing thin-film polymers, ceramics, and medical devices, but applications are far broader. We’ll consider your project’s specifications, required tolerances, and additional details before recommending an excimer or alternative laser micromanufacturing system.
Laser Light Technologies incorporates fundamental, doubled and tripled frequency YAG lasers into micromachining systems. Each laser type has typical system setups and uses, but your specific application is what ultimately drives our laser selection.
Fundamental frequency YAG lasers are ideal for micromachining many metals and ceramics. This type of laser is typically mounted with a short focal length lens inside a gas-assisted nozzle; this combination helps make cleaner edge cuts possible. For most applications, we find oxygen is the ideal assist gas for cut edge quality. For applications with special alloys like Nitinol or MP35N, oxygen is replaced with argon to prevent oxide film formation on cut edges.
For micromachining some plastics and reflective metals such as gold, aluminum and copper, we use doubled frequency YAG lasers with a wavelength of 0.532 nanometers. The laser’s shorter wavelength helps produce a smaller heat affected zone (HAZ) for less edge melting. A typical system includes high-precision mechanical stages and a galvanometer head for faster cycle time and batch processing. By adding software, we can also achieve infinite field of view (IFV), enabling cuts to more of a part’s surface.
We use our triple frequency YAG lasers for micromachining materials with a low tolerance for heat, including multilayer laminates, adhesive films and thin ceramic parts. A shorter wavelength of 0.355 nanometers allows the triple frequency YAG laser beam to focus on a smaller spot size and still maintain the focus depth needed to drill holes. Typical system configurations for this laser are similar to those created for double frequency lasers.
Lasers can execute incredible tasks that aren’t possible any other way, and they’re increasingly valuable in manufacturing today. To ensure your unique needs are met with an ideal solution, Laser Light Technologies has equipment covering the full spectrum of laser wavelengths to process a variety of different applications.
We’re proud to create and operate micromachining systems that make the most of all that lasers have to offer. This takes strategic engineering thinking that considers what’s best for a customer project: technicians or robotic automation; excimer lasers, picosecond lasers, or Nd: YAG lasers; and more.
The goal is always flawless precision. We have instruments with nanometer level accuracy to test and measure what we produce, ensuring we fulfill our promises. We also have reporting processes that give you timely information about what matters most to you.
Laser technology is central to what we do, but the reason we do it is you: our customer.
