Beschreibung Produktfamilie

  • AR-beschichtet für <1,25% Reflexion pro Oberfläche bei 400 - 1000 nm
  • <0,25% Reflexion bei 880 nm
  • Entwickelt für einen Einfallswinkel von 0°
  • Verschiedenste Beschichtungsoptionen: unbeschichtet, VIS-EXTMgF2, VIS 0°, YAG-BBAR, NIR I und NIR II

TECHSPEC® Plankonkave Linsen (PCV) mit VIS-NIR Beschichtung 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) mit VIS-NIR Beschichtung sind für die Transmission (>99%) im nahen Infrarot optimiert. Diese Linsen sind auch unbeschichtet sowie mit den AR-Beschichtungen VIS-EXTMgF2VIS 0°YAG-BBARNIR I oder NIR II erhältlich.
