KBX175AR.14 50.8 mm Dia. x 400 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The KBX175AR.14 is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 400 mm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The lens is made from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The KBX175AR.14 features an anti-reflective (AR) coating, specifically the New AR-14 fromfigure, which is applied to both the front and back surfaces. This coating is designed to operate within the wavelength range of 430-700nm, making it ideal for a wide range of optical applications. The AR coating significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance.
The lens geometry is meticulously designed, with an edge thickness of 3 mm and a center thickness of 4.565 mm. The first and second radii of curvature are 412.674 mm and -412.674 mm, respectively, while the back focal length is 398.49 mm. The lens has an effective focal length (EFL) of 400 mm, and the inner and outer radii are both 0 mm.
