SBX064 50.8 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens
The SBX064 is a spherical lens with a base shape of a circle, sourced from the reputable vendor MKS/Newport. This lens is uncoated, making it suitable for applications where coating is not a requirement. With a diameter of 50.8 mm and a thickness at the edge of 3 mm, it is designed to provide a focal length of 250 mm.
The lens's geometry is intricately designed with an inner radius of 0 and an outer radius of 0, indicating a symmetrical structure. The center thickness is 5.831 mm, and the effective focal length (EFL) is 250 mm. The first radius of curvature (R1) is 228.587 mm, while the second radius of curvature (R2) is -228.587 mm, suggesting a double-convex lens. The back focal length (BFL) is 247.99 mm.
The lens is made of UVFS material, specifically UVFS Mal-1965, and is designed to work optimally with a wavelength of 589 nm. This lens is a great option for those seeking a high-quality, uncoated, double-convex lens for their optical applications.
