  • This field is for validation purposes and should be left unchanged.

Laser Machining is a technology that utilizes a laser to cut materials, and is typically used for industrial manufacturing applications.  Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either, melts, burns, vaporizes away, or is blown away by a jet of gas leaving an edge with a high-quality surface finish.  Conoptics manufactures a complete line of Electro-Optic Modulation Shutter Systems specifically designed to work with High-Power Lasers and Machining applications.
