87-970 50 mm Dia. Germanium Positive Meniscus Lens; EFL=50mm BBAR 8-12µm
This is a 50 mm diameter Germanium positive meniscus lens, featuring an effective focal length (EFL) of 50mm and broadband anti-reflection (BBAR) coating for the 8-12µm wavelength range. The lens is sourced from Edmund Optics and is currently in stock.
The lens has a base shape of a circle and a sub-type of spherical lens with a convex-concave design. The geometry includes a 2.6 mm thickness at the edge, a 5 mm thickness at the center, and a 46.69 mm back focal length (BFL). The first radius of curvature (R1) is 56.64 mm, while the second radius of curvature (R2) is 84.91 mm. The lens's inner and outer radii are both 0 mm.
The lens is made of germanium burnett material, specifically designed for the 10600 nm wavelength. The front and back of the lens are coated with edm arcedgermanium81, providing excellent anti-reflection properties.
