11-434 50.8mm Dia. x 200mm FL; Coated; ZnSe Plano-Convex Lens BBAR 3-12µm
This is a 50.8mm diameter, 200mm focal length plano-convex lens, manufactured from ZnSe material with BBAR coating on both sides. The lens is sourced from Edmund Optics and is currently in stock.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curvature radius (r1) is 280.54mm. The lens's thickness at the edge is 2.35mm, while the center thickness is 3.5mm. The effective focal length (EFL) is 200mm.
The lens is made of ZnSe (Zinc Selenide) material, identified as "znse connolly" in the material ID. This material is known for its excellent transmission in the near and mid-infrared regions, making it suitable for applications in these spectral ranges.
The lens is coated with BBAR (Broadband Anti-Reflection) coating on both sides. This coating reduces reflection and increases transmission, enhancing the lens's performance in the specified wavelength range of 3-12µm.
