SBX025AR.14 25.4 mm Dia. x 75.6 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The SBX025AR.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 75.6 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 SBX025AR.14 features a unique double-convex geometry, with radii of curvature of 68.547 mm for both the front and back surfaces. This geometry results in a high numerical aperture, enhancing the lens's light-gathering capability. The lens has a central thickness of 5.373 mm and an edge thickness of 3 mm, providing robustness and durability.
The 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, improving the overall transmission of the lens. The coating is applied to both the front and back surfaces, ensuring optimal performance from all angles.
