KBX172AR.14 50.8 mm Dia. x 300 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The KBX172AR.14 is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 300 mm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The lens is made from the material n-BK7 schott, a popular choice for its excellent optical properties.
The KBX172AR.14 features an anti-reflective (AR) coating on both the front and back surfaces, utilizing the new AR-14 fromfigure coating. This coating is specifically designed to reduce reflective losses at the lens surfaces, thereby enhancing transmission and image quality. The AR coating is effective within the wavelength range of 430-700nm, making this lens suitable for a wide range of applications.
The lens geometry is spherical, with a center thickness of 5.09 mm and an edge thickness of 3 mm. The inner and outer radii are 0, indicating a uniform curvature. The effective focal length (EFL) is 300 mm, and the back focal length (BFL) is 298.31 mm. The radius of curvature for the first surface (R1) is 309.222 mm, while the second surface (R2) has a radius of curvature of -309.222 mm.
The KBX172AR.14 is available from the vendor's website, where it is currently in stock. This lens is a reliable choice for those seeking a high-performance, double-convex lens with AR coating in the specified wavelength range.
