Disclaimer

Laser induced damage threshold (LIDT) measurements are performed on actual components produced by Altechna. Individual component’s LIDT depends on multiple parameters (substrate material, polishing batch, coating batch, storage conditions, etc). Damage threshold value reached for above individual components should be used for reference only but it is not guaranteed for all optics. Altechna can perform coating damage threshold testing service upon request.
