SPX061AR.4 25.4 mm Dia. x 50.0 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX061AR.4 is a high-energy plano-convex lens, designed and manufactured by MKS/Newport. This lens, with a diameter of 25.4 mm, is specifically engineered for use in the ultraviolet spectrum, with an AR coating optimized for the 230-266nm range.
The lens's geometry is characterized by a thickness of 3 mm at the edge, increasing to 6 mm at the center, and a focal length of 50 mm. The radius of curvature of the convex surface is 23.004 mm, and the back focal length measures 45.89 mm. The lens is made from fused silica (mal-1965), ensuring high transmittance and durability.
The lens's coating, both front and back, is Newport's AR-4, a high-performance anti-reflective coating designed for high-energy applications. This coating significantly reduces surface reflections, enhancing the lens's efficiency and performance in its designated wavelength range.
