87-949 25mm Dia. x 100mm FL; Coated; Ge Plano-Convex Lens BBAR 3-12µm
This is a 25mm diameter, 100mm focal length plano-convex lens made of Germanium burnett, sourced from Edmund Optics. The lens is coated with BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically optimized for the 3-12µm wavelength range.
The lens has a spherical shape with a 300.39mm radius of curvature on the convex side. The center thickness is 3mm, while the edge thickness is 2.74mm. The back focal length (BFL) is 99.25mm, and the effective focal length (EFL) is 100mm. The lens does not have any inner or outer radius specified, indicating a uniform curvature.
The lens is available from Edmund Optics and is currently in stock. For more information, you can refer to the vendor's website using the provided weblink.
