This is a Plano-Convex Lens, type 38-573, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a 9.0mm diameter and a focal length of 25mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is widely used in various optical systems due to its excellent transparency in the visible and near-infrared regions.
The lens features a YAG-BBAR coating on both the front and back surfaces, specifically designed for the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
The geometry of the lens includes a thickness of 1.19mm at the edge and 2mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The lens's base shape is circular, and its shape is spherical, which is a common choice for many optical systems due to its ease of manufacturing and high optical quality.
