KPX115AR.14 25.4 mm Dia. x 400 mm FL; AR coated; Plano-Convex Lens AR 430-700nm
The KPX115AR.14 is a Plano-Convex Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 400 mm, making it suitable for a wide range of optical applications. The lens is fabricated from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens geometry is characterized by its edge thickness of 3 mm and center thickness of 3.39 mm. The inner radius is zero, indicating a plano surface on one side and a convex surface on the other. The effective focal length (EFL) is 400 mm, and the radius of curvature (R1) is 206.72 mm. The back focal length (BFL) is 397.76 mm.
The KPX115AR.14 lens features AR coating on both the front and back surfaces. The coating is specified for the wavelength of 589 nm and has a broadband anti-reflective coating in the range of 430-700 nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and minimizing light loss.
