SPX014AR.4 25.4 mm Dia. x 33.0 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX014AR.4 is a high-energy plano-convex lens, designed and manufactured by MKS/Newport. This lens, with a diameter of 25.4 mm, is part of the AR4 series, known for its high-performance anti-reflective coatings. The lens has a plano-convex geometry, meaning one side is flat (plano), and the other side is curved (convex).
The lens's thickness at the edge is 3 mm, while the center thickness is 9.91 mm. The effective focal length (EFL) is 33 mm, and the radius of curvature (R1) is 15.128 mm. The back focal length (BFL) is 26.21 mm, and the inner radius is 0 mm.
The lens is made of fused silica (mal-1965), a material known for its excellent optical properties and durability. The lens is designed to operate at a wavelength of 589 nm.
The lens features AR coatings on both the front and back surfaces. These coatings are designed to reduce reflection and increase transmission in the 230-266 nm range. This makes the lens ideal for applications that require high transmission and low reflection, such as laser systems, spectroscopy, and imaging.
