SPX059AR.4 25.4 mm Dia. x 300 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX059AR.4 is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 300 mm, making it suitable for a wide range of optical applications. The lens's geometry is designed with a thickness of 3 mm at the edge and 3.586 mm at the center, providing a balanced optical path.
The lens is made from fused sil mal-1965, a high-quality material known for its excellent optical properties. The base shape is circular, ensuring uniform light distribution and minimal distortion. The inner radius of the lens is zero, indicating a direct transition from the planar to the curved surface.
The lens features AR coating on both the front and back surfaces. This AR coating, specifically the new AR-4 fromfigure, is designed to optimize performance within the wavelength range of 230-266nm. The coating reduces reflection and enhances transmission, thereby improving the overall efficiency and quality of the optical system.
