KPX121 25.4 mm Dia. x 750 mm FL; Uncoated; Plano-Convex Lens

The KPX121 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 750 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.

The KPX121 is a Spherical Lens, specifically a Plano-Convex lens, which means one side is flat (plano) and the other side is curved (convex). The lens's geometry includes a thickness edge of 3 mm and a thickness center of 3.208 mm. The effective focal length (EFL) is 750 mm, and the radius of curvature (R1) is 387.6 mm. The back focal length (BFL) is 747.88 mm, and the inner radius is 0 mm.

This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed to work with a wavelength of 589 nm. The lens's base shape is circular, making it suitable for a wide range of applications.
