87-943 25mm Dia. x 25mm FL; Coated; Ge Plano-Convex Lens BBAR 3-12µm

The 87-943 is a 25mm diameter, 25mm focal length plano-convex lens, designed for use with a wavelength of 10600nm. Manufactured by Edmund Optics, this lens boasts a high-quality Germanium material, identified as "germanium burnett" in the item data.

The lens features a front and back coating of "edm arcedgermanium31", which is a broadband anti-reflection (BBAR) coating. This coating is specifically designed to reduce surface reflections, thereby enhancing transmission and improving overall optical performance.

The geometry of the lens is characterized by a 1.95mm edge thickness and a 3mm center thickness. The lens's effective focal length (EFL) is 25mm, and its radius of curvature (R1) is 75.1mm. The back focal length (BFL) is 24.25mm, and both the inner and outer radii are 0mm, indicating a flat surface on the opposite side of the convex curve.

This lens is currently in stock and available for purchase through the provided weblink. With its high-quality Germanium material and BBAR coating, the 87-943 is an excellent choice for applications that require a plano-convex lens with a specific focal length and diameter.
