SBX064AR.14 50.8 mm Dia. x 250 mm FL; AR coated; Double-Convex Lens AR 430-700nm
The SBX064AR.14 is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. This lens, with a diameter of 50.8 mm, is designed for use in the UV-VIS-NIR spectrum, specifically optimized for wavelengths around 589 nm.
The lens features a double-convex geometry, with radii of curvature of r1 = 228.587 and r2 = -228.587. This geometry provides a focal length of 250 mm and an effective focal length of 247.99 mm. The lens has a central thickness of 5.831 mm and an edge thickness of 3 mm, ensuring robustness and durability.
The SBX064AR.14 is coated with New AR-14, a broadband anti-reflective coating that enhances transmission in the 430-700 nm range. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and improving overall system performance.
The lens is made from UVFS Mal-1965, a material with excellent optical properties in the UV-VIS-NIR range. The material ID is provided for users who may need to cross-reference or verify the material properties.
