11-421 12.7mm Dia. x 35mm FL; Coated; ZnSe Plano-Convex Lens BBAR 3-12µm

The 11-421 is a 12.7mm diameter, 35mm focal length plano-convex lens, designed for use in the 3-12µm wavelength range. This lens is sourced from Edmund Optics, a leading provider of optical components.

The lens is made from ZnSe (Zinc Selenide) material, identified by the Material ID "znse connolly". This material is known for its excellent transmission properties in the infrared spectrum, making it ideal for applications such as thermal imaging and spectroscopy.

The lens features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, designated as "edm dbbarl znse 312". This coating reduces reflection losses across the entire spectral range, enhancing the overall transmission of the lens.

The geometry of the lens includes a 2.09mm edge thickness and a 2.5mm center thickness. The lens has a spherical shape, with a radius of curvature (R1) of 49.1mm on the convex side. The inner and outer radii are both zero, indicating a plano surface on the opposite side.

The lens is in stock and available for immediate purchase through the provided weblink. With its high-quality materials, advanced coating, and precise geometry, the 11-421 is a reliable choice for a wide range of infrared optical applications.
