When laser cleaning Lead Crystal, you'll want to start with its soft, lead-infused structure. This makes it more prone to surface damage than regular glass, so it absorbs heat unevenly and risks cracking under direct exposure. Use gentle, low-energy pulses to lift contaminants without etching the crystal's shine. Keep your scan slow and overlap lightly for even coverage. Always watch for clouding at the end, and pause to cool if it appears.

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 and Energy Density. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Energy Density
Higher power delivers more energy per pulse, removing more material.
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.
