89-205 3mm Dia. x 3mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm

The 89-205 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 3mm and a focal length of 3mm, is designed for use in a wide range of optical applications, particularly those requiring precise focusing and imaging.

The lens is constructed from n-sf5 Schott, a high-grade optical material known for its excellent transparency and durability. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 3.5mm and -3.5mm for the first and second surfaces, respectively. This geometry results in a back focal length of 2.21mm and an effective focal length of 3mm.

The lens is coated with YAG-BBAR, a highly durable and efficient coating that enhances its performance in the spectral range of 500-1100nm. This coating reduces surface reflections, thereby improving transmission and enhancing the overall efficiency of the lens.

The 89-205 is currently in stock and available for immediate shipping. Its detailed specifications, including its geometry, material, coating, and spectral range, make it an ideal choice for users seeking a high-performance, compact lens for their optical systems.
