This is a high-quality spherical lens, specifically a double-convex lens, sourced from the reputable vendor MKS/Newport. The lens is designed for use with a 12.7 mm diameter and features a base shape of a circle. The lens has a thickness of 3 mm at the edge and 4.826 mm at the center, providing a robust structure for various applications.
The effective focal length (EFL) of this lens is 25.4 mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 22.532 mm, while 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, which is known for its excellent optical properties. It is designed to work with a wavelength of 589 nm. The lens features a New AR-33 coating on both the front and back surfaces, enhancing its performance in laser applications, particularly at 1064 nm.
