KBX043AR.14 25.4 mm Dia. x 19.0 mm FL; AR coated; Double-Convex Lens AR 430-700nm

The KBX043AR.14 is a high-quality double-convex lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 19.0 mm, making it a versatile choice for a variety of optical applications.

The lens is crafted from n-BK7 Schott, a high-grade optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for applications that require high precision and clarity.

The KBX043AR.14 features a new AR-14 coating on both the front and back surfaces. This anti-reflective coating is designed to operate within the wavelength range of 430-700nm, reducing surface reflections and improving transmission. This makes the lens ideal for use in systems that require high light transmission and minimal reflection, such as imaging systems, beam delivery systems, and laser applications.

The lens geometry includes an inner radius of 0 mm and an outer radius of 0 mm, with a thickness at the edge of 3 mm and a thickness at the center of 14.725 mm. The effective focal length (EFL) is 19 mm, and the back focal length (BFL) is 13.28 mm. The radii of curvature for the first and second surfaces are 16.687 mm and -16.687 mm, respectively.
