11-408 50.8mm Dia. x 50.8mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm
The 11-408 is a Plano-Convex Spherical Lens, boasting a diameter of 50.8mm and a focal length of 50.8mm, specifically designed for use with a wavelength of 10600nm. This lens is sourced from Edmund Optics, a trusted vendor in the optical industry.
The lens is constructed from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the Material ID field. This material is known for its excellent transmission properties in the infrared region, making it suitable for a wide range of applications in this spectrum.
The lens features a front and back coating of "edm dbbarl znse 812", which is a type of Broadband Anti-Reflective (BBAR) coating. This coating is designed to reduce surface reflections, thereby enhancing the transmission of light through the lens. The BBAR coating is particularly effective over a broad range of wavelengths, from 8µm to 12µm, making this lens ideal for use in mid-infrared (MIR) applications.
The geometry of the lens includes a thickness of 2.42mm at the edge and 7.1mm at the center. The inner and outer radii are both zero, indicating a plano-convex shape. The effective focal length (EFL) of the lens is 50.8mm, which is equal to its focal length, as the lens is a simple plano-convex design.
