11-412 50.8mm Dia. x 200mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm

The 11-412 is a high-quality plano-convex lens offered by Edmund Optics, designed for use in the infrared spectrum with a wavelength of 10600nm. This lens boasts a diameter of 50.8mm and a focal length of 200mm, making it suitable for a wide range of optical applications.

The lens is crafted from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the material ID. This material is known for its excellent transmission properties in the infrared region, making it an ideal choice for this lens. The lens features a front and back coating of "edm dbbarl znse 812", which is a broadband anti-reflection coating specifically designed for ZnSe in the 8-12µm range. This coating helps to reduce surface reflections, thereby improving the overall efficiency and performance of the lens.

The geometry of the lens includes a thickness of 2.35mm at the edge and 3.5mm at the center. The inner and outer radii are both zero, indicating a simple plano-convex design. The lens's base shape is circular, adding to its versatility in various optical systems.
