KBX178AR.33 50.8 mm Dia. x 500 mm FL; Double-Convex Lens Laser V-Coat 1064nm
The KBX178AR.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 500 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 versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 516.098 mm for the first surface and -516.098 mm for the second surface. This geometry results in a high degree of convergence, making it ideal for focusing light.
The KBX178AR.33 is coated with a new AR-33 coating on both the front and back surfaces. This coating is specifically designed to reduce reflection at the 1064 nm wavelength, enhancing the lens's performance in laser applications. The coating also provides excellent environmental resistance, ensuring the lens maintains its performance over time.
The lens has a thickness of 3 mm at the edge and 4.251 mm at the center. The back focal length is 498.59 mm, and the inner and outer radii are 0 mm, indicating a uniform curvature.
