KPX121-C 25.4 mm Dia. x 750 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX121-C 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 made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

The lens features a MgF2 coating on both the front and back surfaces. This coating is known for its superior anti-reflection properties, reducing reflective losses and improving transmission in the spectral range of 400-700 nm. The MgF2 coating also provides excellent environmental stability, making it suitable for use in various applications.

The KPX121-C has a thickness of 3 mm at the edge and 3.208 mm at the center. The inner radius is 0, indicating a plano surface on the other side of the lens. The effective focal length (EFL) is 750 mm, and the back focal length (BFL) is 747.88 mm. The radius of curvature (R1) is 387.6 mm.

This lens is ideal for applications that require high-quality imaging and light transmission in the visible spectrum. Its robust construction and reliable performance make it a popular choice among optical professionals and researchers.
