Thanks for the information. I wasn't really looking for a clean cut. At work, we have a machine to help recycle old tv and computer screens, separating the front part of the CRT's glass from the cone part. This is done by scouring the glass with a carbide wheel and then applying heat with a resistive tape to help crack the glass. The system is so inefficient and I thought the laser could help. |

We recently had some discussion (in another forum) where I doubted that laser produced lithophanes could actually produce a resolution equal to a spindle engraved litho but since getting hold of some genuine Corian to try - I now think that it is possible to get extremely close. The big advantage is that the laser takes half an hour to produce a small, 0.1mm step-over, litho that may take half a day with spindle engraving. This litho (created from a .jpg image of the Hungarian Parliament Building) is just 50mm square and I think is probably a good example of the resolution that is typically achievable using laser techniques.
