SBX018 25.4 mm Dia. x 20.0 mm FL; Uncoated; Double-Convex Lens
The SBX018 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 required or preferred. The lens is designed with a double-convex structure, meaning it has two convex surfaces.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2.602 mm. The center thickness is significantly greater at 14.5 mm. The effective focal length (EFL) of this lens is 20 mm. The first radius of curvature (R1) is 15.388 mm, while the second radius of curvature (R2) is -15.388 mm, indicating the double-convex structure.
The back focal length (BFL) of this lens is 13.45 mm. The inner and outer radii are both 0, suggesting that this lens does not have any special shaping on its inner or outer edges.
The lens is made from UVFS material with the ID of MAL-1965. It is designed to work with a wavelength of 589 nm. This lens is currently in stock and available for immediate purchase, as indicated by its valid web link status.
