SPX031 25.4 mm Dia. x 500 mm FL; Uncoated; Plano-Convex Lens
The SPX031 is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a diameter of 25.4 mm and a center thickness of 3.352 mm, with an edge thickness of 3 mm. The lens is designed for a focal length of 500 mm and has an effective focal length (EFL) of the same value.
The lens's curvature is defined by a radius of 229.5 mm on the convex side, and an inner radius of 0 mm, indicating a plano surface on the other side. The back focal length (BFL) of the lens is 497.7 mm. The lens is made of UVFS material with the ID MAL-1965, and it is uncoated.
This lens is suitable for applications that require a simple, uncoated lens with a long focal length. The uncoated surface may introduce some reflection, but it also reduces the cost compared to coated lenses. The lens's large diameter and long focal length make it suitable for applications that require a wide field of view and high magnification.
