11-418 12.7mm Dia. x 12.7mm FL; Coated; ZnSe Plano-Convex Lens BBAR 3-12µm

The 11-418 is a 12.7mm diameter, 12.7mm 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, spectroscopy, and other infrared-based technologies.

The lens features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, designated as "edm dbbarl znse 312". This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.

The geometry of the lens includes a diameter of 12.7mm, an edge thickness of 1.83mm, and a center thickness of 3mm. The lens has a spherical shape, with a radius of curvature (r1) of 17.81mm on the convex side. The lens does not have an inner or outer radius.

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 11-418 is a reliable and versatile choice for a wide range of infrared applications.
