KBX148AR.14 50.8 mm Dia. x 75.6 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The KBX148AR.14 is a high-quality double-convex lens, sourced from the reputable vendor MKS/Newport. This lens, with a diameter of 50.8 mm and a focal length of 75.6 mm, is designed for use in the visible spectrum, specifically optimized for wavelengths between 430 and 700 nm.
The lens is made from the material n-BK7 schott, a popular choice in the optical industry due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 11.729 mm and an edge thickness of 3 mm. The effective focal length (EFL) is 75.6 mm, and the back focal length (BFL) is 71.63 mm.
The KBX148AR.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 optimally within the specified wavelength range.
