The SPX015 is a Plano-Convex Lens with a diameter of 25.4 mm and a focal length of 38.1 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular. The thickness at the edge of the lens is 3 mm, while the center thickness is 8.48 mm. The effective focal length (EFL) is 38.1 mm, and the radius of curvature (R1) is 17.465 mm. The back focal length (BFL) is 32.29 mm, and the inner radius is 0 mm.
The lens is made of UVFS Mal-1965, a material with a refractive index suitable for use in the visible light spectrum, specifically at a wavelength of 589 nm. The lens's shape is spherical, which is a common type of lens used in various optical applications due to its simple design and manufacturing process.
The item data does not provide information about any coatings on the lens. Therefore, it is assumed that the lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or protect the lens surface. However, in this case, the lens does not have any of these additional layers.
