SPX029AR.12 25.4 mm Dia. x 250 mm FL; AR coated; Plano-Convex Lens AR 1064/532nm
The SPX029AR.12 is a high-energy plano-convex lens, designed and manufactured by MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 250 mm, making it suitable for a wide range of optical applications. The lens is constructed with a fused silica material, identified as mal-1965 in the material database, ensuring durability and high optical quality.
The lens features a plano-convex geometry, with a center thickness of 3.71 mm and an edge thickness of 3 mm. The inner radius of the lens is zero, indicating a flat surface on the opposite side of the convex surface. The effective focal length (EFL) of the lens is 250 mm, and the back focal length (BFL) is 247.46 mm. The radius of curvature of the convex surface is 114.603 mm.
The lens is coated with a new AR-12 coating on both the front and back surfaces. This anti-reflection coating is specifically designed to reduce reflection at the wavelengths of 1064 nm and 532 nm, making it ideal for use in laser applications. The coating ensures high transmission and minimal loss of light, enhancing the overall performance of the lens.
