Beschreibung Produktfamilie

Verfügbar unbeschichtet sowie BBAR-beschichtet für UV, VIS und NIR
Ideal für Bildverarbeitungsanwendungen
Rund oder rechteckig mit Größen von 5 bis 200 mm
1λ- oder λ/10-Fenster aus UV-Quarzglas sind ebenfalls verfügbar

TECHSPEC^® λ/4-Fenster aus UV-Quarzglas haben eine Oberflächenqualität von 40-20 und einen transmittierten Wellenfrontfehler von λ/4. Dies macht sie ideal für Bildverarbeitungsanwendungen. Die Fenster bestehen aus UV-Quarzglassubstraten und bieten eine hohe Transmission vom ultravioletten über den sichtbaren bis zum nahinfraroten Bereich. Es sind breitbandige Antireflexionsbeschichtungen (BBAR) verfügbar, um Reflexionsverluste zu minimieren und die Transmission zu erhöhen. TECHSPEC^® λ/4-Fenster aus UV-Quarzglas werden in optischen Bildgebungsanwendungen, in Laseranwendungen mit geringer oder mittlerer Leistung und als Schutzfenster für Anwendungen, die eine hohe UV-Transmission erfordern, eingesetzt.
