SBX013 12.7 mm Dia. x 12.7 mm FL; Uncoated; Double-Convex Lens
The SBX013 is a spherical lens with a base shape of circular, sourced from the reputable vendor MKS/Newport. This lens is a part of their uncoated UVFS bi-convex series, designed for general-purpose use. The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm, ensuring durability and stability. The center thickness is 7.349 mm, providing a balanced structure for various applications.
The SBX013 has an effective focal length (EFL) of 12.7 mm, which is the same as its diameter, indicating a double-convex lens. The first radius of curvature (R1) is 10.358 mm, while the second radius (R2) is -10.358 mm, confirming its double-convex nature. The back focal length (BFL) is 9.86 mm, which is a critical factor in determining the lens's performance in specific applications.
This lens is made from UVFS material with the ID 1965, optimized for a wavelength of 589 nm. The lens is uncoated, offering a clear, unaltered view of the light path. However, users should be aware that uncoated lenses may have higher reflectivity and lower transmission compared to coated lenses.
