This KPX088AR.33 lens, sourced from MKS/Newport, is a Plano-Convex Spherical Lens with a diameter of 25.4 mm and a focal length of 75.6 mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability.
The lens's geometry includes an edge thickness of 3 mm and a center thickness of 5.122 mm. The lens's effective focal length (EFL) is 75.6 mm, and the radius of curvature (R1) is 39.07 mm. The back focal length (BFL) is 72.22 mm, and the inner radius is 0 mm.
The lens features a V-Coat coating on both the front and back surfaces. This coating, specifically AR-33 from Figure, is designed to minimize reflection at a wavelength of 1064 nm. The lens's shape is spherical, and it is available for purchase directly from the vendor's website, where it is currently in stock.
