This is a high-quality Spherical Lens (Convex-Convex) type optical component, sourced from the reputable vendor MKS/Newport. The lens, identified as SBX016AR.10, has a base shape of a circle and is designed for use with a wavelength of 589 nm.
The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm. The center thickness is 4.826 mm, and the effective focal length (EFL) is 25.4 mm. The first radius of curvature (R1) is 22.532 mm, and the second radius of curvature (R2) is -22.532 mm, indicating a double-convex design. The back focal length (BFL) is 23.68 mm.
The lens is made from UVFS Mal-1965 material, and it comes with AR-10 coating on both the front and back surfaces. This coating enhances the lens's performance in the UV spectrum, specifically between 245-440 nm. The lens is UV coated, making it suitable for applications that require transmission of ultraviolet light.
Please note that the inner and outer radii are both 0, indicating that this lens does not have any special features such as a thread or a flange.
