SBX040AR.14 25.4 mm Dia. x 500 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The SBX040AR.14 is a high-quality double-convex lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 500 mm, making it suitable for a wide range of optical applications. The lens is constructed from UVFS MAL-1965, a material known for its excellent optical properties.
The SBX040AR.14 features a unique double-convex geometry, with radii of curvature of 458.46 mm for the first surface and -458.46 mm for the second surface. This geometry results in an effective focal length (EFL) of 500 mm and a back focal length (BFL) of 498.85 mm. The lens has a center thickness of 3.35 mm and an edge thickness of 3 mm, providing robustness and durability.
This lens is coated with New AR-14, a broadband anti-reflective coating designed for use in the 430-700 nm wavelength range. This coating significantly reduces surface reflections, enhancing the overall performance of the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and minimal loss.
