KBX172AR.33 50.8 mm Dia. x 300 mm FL; Double-Convex Lens Laser V-Coat 1064nm
The KBX172AR.33 is a high-quality double-convex lens, designed and manufactured by MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of 300 mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high transparency in the visible and near-infrared regions. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 309.222 mm for both the front and back surfaces.
The KBX172AR.33 is coated with New AR-33, a broadband anti-reflective coating specifically designed for 1064 nm lasers. This coating ensures high transmission and low reflection, enhancing the lens's performance in laser applications. The coating is applied to both the front and back surfaces of the lens.
The lens has a thickness of 3 mm at the edge and 5.09 mm at the center. The effective focal length (EFL) is 300 mm, and the back focal length (BFL) is 298.31 mm. The lens does not have any inner or outer radii.
