This is a 3.0mm diameter x 12.0mm focal length Plano-Convex lens, offered by Edmund Optics. The lens is made from n-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high homogeneity.
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 reflection and increasing transmission, making it ideal for applications that require high light transmission, such as laser systems, imaging systems, and optical metrology.
The lens's geometry includes a 0.9mm thickness at the edge and a 1.08mm thickness at the center. The front surface has a radius of curvature of 6.2mm, resulting in a back focal length of 11.29mm. The lens's shape is spherical, which is a common choice for many optical applications due to its simplicity and wide range of available materials.
The lens's information is available on the Edmund Optics website, where you can find more details and purchase this product. The link is valid and indicates that the lens is in stock, ensuring quick delivery for your optical project needs.
