69-652 25mm Dia. x 40mm FL; Coated; Ge Plano-Convex Lens BBAR 3-5µm
This 69-652 optical lens, sourced from Edmund Optics, is a Spherical Lens of the Plano-Convex type, designed with a Circular base shape. The lens boasts a diameter of 25mm and a thickness at the edge of 2.35mm, while the center thickness is 3mm. The Effective Focal Length (EFL) of the lens is 40mm, and the Radius of Curvature (R1) is 120.16mm. The Back Focal Length (BFL) is 39.25mm, and both the Inner and Outer Radius are 0mm.
The lens is crafted from Germanium Burnett material, optimized for a wavelength of 10600nm. It features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically the 'edm arcedgermanium35' coating. This coating enhances the lens's performance by minimizing surface reflections and improving transmission efficiency.
