SBX031 25.4 mm Dia. x 150 mm FL; Uncoated; Double-Convex Lens
The SBX031 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 or preference. The lens features a diameter of 25.4 mm and a thickness at the edge of 3 mm, ensuring durability and stability. The center thickness is 4.179 mm, providing a solid base for optical applications.
The effective focal length (EFL) of this lens is 150 mm, making it suitable for medium to long-range optical systems. The first radius of curvature (R1) is 137.045 mm, and the second radius of curvature (R2) is -137.045 mm, indicating a double-convex lens design. The back focal length (BFL) is 148.56 mm, which is crucial for determining the position of the lens in an optical system.
The lens is made from UVFS material with the ID 1965, optimized for a wavelength of 589 nm. This makes it suitable for applications that require high transmittance at this specific wavelength. The lens's shape is spherical, which is a common choice for its excellent optical properties and ease of manufacturing.
