25.0mm Dia. x 250.0mm FL; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm
This is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 25.0mm and a focal length of 250.0mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and chemical durability.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, specifically designed for the wavelength range of 500-1100nm, enhances the lens's performance by reducing surface reflections and increasing transmission. The coating is particularly beneficial in applications where high transmission and low loss are critical, such as in laser systems, beam delivery systems, and imaging systems.
The geometry of the lens is meticulously designed, with a thickness of 2.39mm at the edge and 3mm at the center. The lens's inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 129.2mm, and the back focal length is 248.02mm.
