Beschreibung Produktfamilie

  • Wellenlängenbereich 400 - 2200 nm
  • Präzise Durchmesser- und Zentrierungstoleranzen ermöglichen eine einfache Integration in OEM-Systeme
  • Große Auswahl an Durchmessern, Brennweiten und Beschichtungen
  • Verfügbare Antireflexionsbeschichtungen: VIS-EXTMgF2, VIS 0°, VIS-NIR, YAG-BBARNIR I und NIR II

TECHSPEC® Plankonkave Linsen (PCV), unbeschichtet, sind so konstruiert, dass sie parallele Eingangsstrahlen auf der Ausgangsseite der Linse auseinanderlaufen lassen, wodurch diese Linse eine negative Brennweite hat. Aufgrund ihrer negativen sphärischen Aberration lassen sich mit diesen Linsen Aberrationen ausgleichen, die durch andere Linsen innerhalb eines Systems entstehen. Plankonkave Linsen (PCV-Linsen) werden häufig in Anwendungen zur Bildverkleinerung und Strahlaufweitung sowie in Teleskopen eingesetzt. TECHSPEC® Plankonkave Linsen (PCV), unbeschichtet, bieten optimale Leistung im Bereich von 350 nm bis 2200 nm. Diese Linsen sind auch mit den AR-Schichtungen VIS-EXT, MgF2VIS 0°VIS-NIRYAG-BBARNIR I, oder NIR II erhältlich.
