Die TECHSPEC® Keilfenster aus UV-Quarzglas haben einen Keilwinkel zwischen 30 Bogenminuten und 10°. Der Keil der Fenster eliminiert Etalon-Effekte, indem verhindert wird, dass Rückreflexionen den gleichen optischen Strahlengang haben wie der transmittierte Strahl. Dies schützt bei einem Einsatz innerhalb des Laserresonators vor Laserinstabilität, Modensprüngen und Leistungsspitzen und bei einem Einsatz außerhalb vor Strahlinterferenzeffekten. Die TECHSPEC® Keilfenster aus UV-Quarzglas sind ideal für den Einsatz in Laseranwendungen im UV oder mit hoher Leistung, da sie eine hohe UV-Transmission und Unempfindlichkeit gegenüber Temperaturschwankungen bieten. Keilfenster können auch als Strahl-Sampler oder Auskopplungs-Optik genutzt werden, um Laserstrahleigenschaften wie die Strahlleistung über eine gewisse Zeitspanne zu beobachten.
