KBX157AR.33 50.8 mm Dia. x 125 mm FL; Double-Convex Lens Laser V-Coat 1064nm
The KBX157AR.33 is a high-quality double-convex lens, designed and manufactured by MKS/Newport, a leading vendor in the optical industry. This lens boasts a diameter of 50.8 mm and a focal length of 125 mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 127.811 mm for the first surface and -127.811 mm for the second surface. This geometry results in a high numerical aperture, enhancing the lens's light-gathering capability.
The KBX157AR.33 is coated with New AR-33 fromfigure on both the front and back surfaces. This anti-reflection coating is specifically designed for use with 1064 nm lasers, reducing surface reflections and improving transmission. The coating ensures optimal performance in laser applications, enhancing the overall efficiency and effectiveness of the system.
The lens has a thickness of 3 mm at the edge and 8.098 mm at the center, providing excellent structural integrity. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface. The effective focal length (EFL) is 125 mm, and the back focal length (BFL) is 122.3 mm.
