Using a 25W CO2 laser, an FH Series Marking Head, and WinMark Pro Laser Marking Software, you can create a decorative, sandblasted look on glass. This decoration was created by importing a bitmap image into WinMark Pro.  A 370mm lens with a 540-micron spot allows us to obtain a "sandblasted" image as large as 9.5 by 11.7inches.

   In WinMark Pro, we set a Power level of 12W, a mark Velocity of 30 inches per second and a marking Resolution of 200.  In addition, Bidirectional Raster was set to "No" and a Vertical Raster Scan Direction was chosen. To limit heat input and thus fracturing, we set WinMark's Spot Marking Style to"Yes" and set a Spot Mark Duration of 100 microseconds. 

   Text, Bar Codes, and Data Matrix codes can also be laser marked on glass to resemble sandblasting.  Click here for more information on this process.
