When laser cleaning sapphire glass, watch its extreme hardness first. It resists contaminants well but can crack under sudden heat. We've found that starting with gentle pulses avoids this. This material stands out for its heat resistance in tough spots like watches or medical gear. Low expansion keeps it stable, unlike softer glasses. We typically use steady scans to clear grime without scratching. Just adjust overlap for even coverage. Skip high speeds—they scatter debris. In our experience, this restores shine safely every time.

Directly affects Scan Speed and Energy Density. Increase this to amplify downstream effects.
Smaller spots concentrate energy into a smaller area.
A bigger spot lets you scan faster while keeping good coverage.
