Beschreibung Produktfamilie

Ideal für die Bildgebung
Minimieren Aberrationen wie sphärische Aberration oder Koma
DCX-Linsen aus UV-Quarzglas sind ebenfalls verfügbar
Antireflexionsbeschichtungen erhältlich: MgF₂, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT und YAG-BBAR

Die TECHSPEC^® unbeschichteten doppelkonvexen Linsen (DCX-Linsen), auch bikonvexe Linsen genannt, haben zwei positive, symmetrische Oberflächen mit gleichem Krümmungsradius auf beiden Seiten. Die Linsen werden generell für Bildgebungen mit endlichem Abstand und Konjugiertenverhältnis (Verhältnis zwischen Objekt- und Bildweite) zwischen 0,2 und 5 empfohlen. Bei einem Konjugiertenverhältnis von 1 sind Aberrationen wie sphärische Aberration, chromatische Aberration, Koma und Verzeichnung aufgrund des symmetrischen Linsendesigns minimiert oder sogar ganz eliminiert. Die TECHSPEC^® unbeschichteten doppelkonvexen Linsen sind mit verschiedenen Substraten und verschiedenen Beschichtungsoptionen für VIS und NIR verfügbar.
