💡 Why do high-damage-threshold coatings matter in laser optics?
High-damage-threshold coatings play a key role in protecting laser systems from wear.
- They reduce reflection losses to boost efficiency in high-power applications
- They prevent debris buildup that could cause downtime in industrial setups
- They extend the lifespan of components by handling intense heat and splatter
- They ensure safer operations by minimizing risks like cracking or contamination
