This product is a Plano-Convex lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as item number 38-589, boasts a diameter of 12.5mm and a focal length of 50.0mm, making it a versatile choice for various optical applications.
The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it an ideal choice for a wide range of wavelengths.
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 applied using Edmund Optics' proprietary YAG-BBAR process, ensuring durability and reliability.
The geometry of the lens is meticulously designed, with an edge thickness of 1.23mm and a center thickness of 2mm. The lens's inner and outer radii are 0mm, indicating a uniform curvature. The lens's front surface has a radius of curvature of 25.84mm, while the back surface has a radius of curvature of 48.68mm. The back focal length of the lens is 48.68mm, and the effective focal length is 50mm.
