Laser Engraving and Marking
Laser Light Technologies, Inc has its roots in laser marking, a process of creating surface contrast using a range of physical effects. Surface effects for laser marking include:
Surface oxidation (stainless steel, titanium, wood, and many plastics):
- Coating underlying substrate with low thermally conducting materials (anodized aluminum and silicon nitride)
- Thermally induced surface cracks (glass)
- Melting and re-solidification to increase surface roughness ( Al2O3/SiN ceramics, silicon, gold, platinum, and select plastics)
- Deposition of target material on a desired substrate (quartz using a ceramic target with inverted material transfer)
In contrast, laser engraving creates surface contrast by the removal of material, typically .005” to .02″ in depth.
Laser Light Technologies can laser mark or laser engrave any shape or illustration, identification, and a variety of automatic ID codes, including but not limited to Data Matrix, Dot Matrix, Code 3 of 9, Interleaved 2 of 5, and many others. We have character recognition systems and 2D readers to verify and grade marks to ANSI Standards. Areas of applications include medical, semiconductor, MEMS, aerospace and automotive industries.
Laser Light specializes in laser marking and laser engraving anodized aluminum, stainless steel, titanium, gold, silver, nickel, silicon, wood, glass, acrylic, delrin, and a variety of polymers. We also have the capability of putting a permanent laser mark on the inner surface of rings. We can mark any font or custom logo you specify.
With an unlimited font selection, Laser Light has capabilities of marking alphanumeric characters
as small as 20-microns in height with our smallest stroke width being 6 microns at an engraved depth of 0.1″ or deeper. Our typical working area is up to 18”X24″, which can be extended to fit your needs. We employ X/Y/Z micropositioning stages and rotary indexers integrated to hold positional tolerances of greater than +/- .001″. Logos and text can be machined on flat, cylindrical, and/or curved surfaces.
