111-1526E 50.8 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens
The 111-1526E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens is a double-convex type, meaning it has two convex surfaces. The lens has a diameter of 50.8 mm and a thickness at the edge of 3.3 mm, while the center thickness is 6 mm. The effective focal length (EFL) of this lens is 250 mm.
The lens's first radius of curvature (R1) is 237.1 mm, and the second radius of curvature (R2) is -237.1 mm, indicating the double-convex nature of the lens. The inner and outer radii are both 0, suggesting a symmetrical design.
This lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet spectrum at a wavelength of 355 nm. The lens does not come with any coating, as indicated by the empty 'coating' parameter in the item data.
