KBX025AR.14 12.7 mm Dia. x 19.0 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The KBX025AR.14 is a high-quality double-convex lens, sourced from the reputable vendor MKS/Newport. This lens, with a diameter of 12.7 mm and a focal length of 19 mm, is designed for use in the visible spectrum, specifically optimized for wavelengths between 430 and 700 nm.
The lens is made from N-BK7 Schott, a popular borosilicate glass known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a spherical geometry, with radii of curvature R1 and R2 at 18.705 mm and -18.705 mm respectively. The lens has a central thickness of 5.22 mm and an edge thickness of 3 mm, providing robustness and stability.
The KBX025AR.14 is coated with a new AR-14 coating on both the front and back surfaces. This anti-reflective coating enhances the lens' performance by reducing surface reflections, thereby increasing transmission and improving image quality. The coating is designed to work within the 430-700 nm wavelength range, making it ideal for applications such as fluorescence microscopy, spectroscopy, and other optical systems operating in the visible spectrum.
