SBX067 50.8 mm Dia. x 500 mm FL; Uncoated; Double-Convex Lens
The SBX067 is a high-quality, spherical lens offered by MKS/Newport, boasting a 50.8 mm diameter and a focal length of 500 mm. This uncoated, double-convex lens is designed for use in a wide range of applications, particularly where precision and clarity are paramount.
The lens's geometry is characterized by its base shape, which is circular, and its thickness at the edge and center. The edge thickness measures 3 mm, while the center thickness is 4.409 mm. The effective focal length (EFL) is 500 mm, and the radii of curvature for the first and second surfaces are 458.325 mm and -458.325 mm, respectively. The back focal length (BFL) is 498.48 mm, and both the inner and outer radii are 0 mm.
The lens is made from UVFS material, specifically UVFS mal- 1965, and is optimized for use at a wavelength of 589 nm. The lack of coating on this lens, while reducing its cost, may make it more susceptible to environmental factors and could affect its transmission characteristics. However, it is still a reliable and efficient option for many applications.
