Laser Materials ProcessingBorosilicate Glass Laser Cleaning Settings
We've found that when laser cleaning borosilicate glass, you need to start with gentle power levels right away, since its brittle nature compared to tougher metals can lead to cracks if heat builds up too fast. Begin by scanning slowly to let its superior heat resistance—unlike everyday soda-lime glass—absorb energy without shocking the surface. Then, increase passes gradually, overlapping beams to clear contaminants evenly while preserving the glass's clarity and strength for lab or medical uses.

Parameter Relationships
Shows how changing one parameter physically affects others. Click any node to see its downstream impacts and role.
Power Range
Amplifies damage risk in Pulse Width. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Pulse Width
More power means higher peak intensity. Too much can damage the material.
Pass Count
Using more passes means you can use lower power and still get the job done.
