The SPX031AR.10 is a Plano-Convex Lens, a type of spherical lens, manufactured by MKS/Newport. This lens has a diameter of 25.4 mm and a focal length of 500 mm, making it suitable for a wide range of optical applications. The lens is made from UVFS material with the ID 1965, and it is designed to work optimally with a wavelength of 589 nm.
The lens features Anti-Reflective (AR) coating on both the front and back surfaces. This coating, specifically the new AR-10 fromfigure, is designed to minimize reflection and increase transmission in the 245-440 nm range. The thickness of the lens at the edge is 3 mm, while the center thickness is 3.352 mm. The lens's inner radius is 0 mm, and its effective focal length (EFL) is 500 mm.
The lens's front surface has a radius of curvature (R1) of 229.5 mm, and its back focal length (BFL) is 497.7 mm. The lens is circular in base shape and is available directly from MKS/Newport, as indicated by the valid in-stock status on the company's website.
