11-422 12.7mm Dia. x 50.8mm FL; Coated; ZnSe Plano-Convex Lens BBAR 3-12µm
The 11-422 is a high-quality Plano-Convex lens, boasting a 12.7mm diameter and a focal length of 50.8mm, specifically designed for use in the 3-12µm wavelength range. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed from ZnSe (Zinc Selenide) material, identified by the Material ID "znse connolly". This material is known for its excellent transparency in the infrared spectrum, making it an ideal choice for applications such as thermal imaging, night vision, and other infrared-based technologies.
The lens features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, denoted as "edm dbbarl znse 312". This coating significantly reduces surface reflections, thereby enhancing the overall transmission of light through the lens. The geometry of the lens includes a thickness of 1.72mm at the edge and 2mm at the center, with no inner or outer radius specified.
