SPX031AR.UF 25.4 mm Dia. x 500 mm FL; NIR coated; Plano-Convex Lens NIR 660-1380nm

The SPX031AR.UF is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 500 mm, making it suitable for a wide range of applications. The lens is made from UVFS MAL-1965, a material known for its excellent optical properties.

The lens features a front and back coating of new aruf6601380, a specialized coating designed for use in the near-infrared (NIR) spectrum, specifically between 660 and 1380 nanometers. This coating enhances the lens's performance in the NIR range, making it an ideal choice for applications that require superior NIR transmission.

The lens's geometry is carefully designed to optimize its performance. It has an edge thickness of 3 mm and a center thickness of 3.352 mm. The lens's effective focal length (EFL) is 500 mm, and its radius of curvature (R1) is 229.5 mm. The back focal length (BFL) is 497.7 mm, and the inner radius is 0 mm.

The lens's base shape is circular, and its type is spherical, which is a common and versatile lens type. The lens's coating and material make it particularly suitable for use in the NIR spectrum, and its Plano-Convex design ensures excellent optical performance.
