89-212 5mm Dia. x 10mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm

The 89-212 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 5mm diameter and a 10mm focal length (FL), making it suitable for a wide range of applications that require compact, high-performance optical elements.

The lens is crafted from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 9.98mm for the first surface and -9.98mm for the second surface. This geometry results in a back focal length (BFL) of 9.31mm and an effective focal length (EFL) of 10mm.

The 89-212 lens is coated with YAG-BBAR, a highly durable and efficient coating that operates within the 500-1100nm wavelength range. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.

The lens is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. This lens is an excellent choice for users seeking a reliable, high-performance optical component for their optical systems.
