Beschreibung Produktfamilie

TECHSPEC® Plankonkave Linsen (PCV) mit MgF2-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 MgF2-Beschichtung sind ideal für Breitbandanwendungen. Diese Linsen sind auch unbeschichtet sowie mit den AR-Beschichtungen VIS-EXTVIS 0°VIS-NIRYAG-BBARNIR I oder NIR II erhältlich.
