87-966 50 mm Dia. Germanium Positive Meniscus Lens; EFL=100mm BBAR 3-5µm

This is a 50 mm diameter Germanium positive meniscus lens, featuring an effective focal length (EFL) of 100mm and broadband anti-reflection (BBAR) coating for a wavelength of 10600 nm with a 3-5 µm thickness. The lens is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.

The lens is a spherical design, with a base shape of a circle. It has a convex-concave sub-type and is made of germanium burnett material. The geometry of the lens includes an edge thickness of 3.8 mm and a center thickness of 5 mm. The first radius of curvature (r1) is 107.03 mm, while the second radius (r2) is 160.46 mm. The back focal length (bfl) is 96.49 mm, and both the inner and outer radii are 0.

The lens is coated on both the front and back with edm arcedgermanium35, providing excellent anti-reflection properties. This coating is specifically designed for germanium and operates within the 3-5 µm wavelength range. The lens is a positive meniscus type, which means it is thicker at the center than at the edges, and it is designed to converge light rays.
