KPX190AR.14 50.8 mm Dia. x 125 mm FL; AR coated; Plano-Convex Lens AR 430-700nm

The KPX190AR.14 is a Plano-Convex Spherical Lens, sourced from the renowned optical components manufacturer, MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of 125 mm, making it suitable for a wide range of optical applications.

The lens is fabricated from N-BK7 Schott, a popular optical crown glass known for its excellent homogeneity, low optical dispersion, and high transmittance in the visible spectrum. The base shape of the lens is circular, and it features an inner radius of 0 mm, indicating a plano surface on one side and a curved surface on the other.

The KPX190AR.14 lens is coated with New AR-14 on both the front and back surfaces. This anti-reflective coating is designed to operate within the wavelength range of 430-700 nm, ensuring high transmission and minimal reflection losses. The edge thickness of the lens is 3 mm, while the center thickness is 8.203 mm, providing robustness and stability.

The lens's geometry includes a radius of curvature (R1) of 64.6 mm and a back focal length (BFL) of 119.59 mm. The effective focal length (EFL) is 125 mm, which is the distance from the lens's principal plane to the focal point.
