88-862-INK 18.0mm Dia. x 18.0mm FL; Inked; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm

This is a YAG-BBAR coated plano-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 88-862-INK, boasts a diameter of 18.0mm and a focal length of 18.0mm, making it a versatile choice for various optical applications.

The lens is constructed from Schott's n-SF11 material, a lead-silicate glass known for its excellent optical properties, including high refractive index and low dispersion. This material makes the lens suitable for use across a wide range of the spectrum, with a specified wavelength of 587.6nm.

The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The radius of curvature of the convex side is 14.13mm, and the back focal length is 15.2mm. The lens has a central thickness of 5.0mm and an edge thickness of 1.76mm, providing a robust structure while maintaining a relatively compact form factor.

The lens is coated with YAG-BBAR (Yttrium Aluminum Garnet - Broad Band Anti-Reflection) coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection losses and increasing transmission within the 500-1100nm wavelength range. The coating ensures optimal light transmission, making the lens ideal for use in laser applications, imaging systems, and other optical setups.
