111-1122E 12.7 mm Dia. x 100 mm FL; Uncoated; Double-Convex Lens
The 111-1122E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens is a part of their UV-FS Biconvex Lenses category, featuring a diameter of 12.7 mm and a focal length of 100 mm. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is double-convex, meaning it has two spherical surfaces that curve outwards. The first surface has a radius of curvature (R1) of 94.8, while the second surface has a radius of curvature (R2) of -94.8. This specific curvature allows the lens to focus light effectively, making it suitable for various applications.
The lens has a center thickness of 2.3 mm and an edge thickness of 1.9 mm. The effective focal length (EFL) is 100 mm, which is the distance from the lens's secondary principal plane to the point at which a collimated beam of light is focused.
The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet spectrum. The wavelength of this lens is 355 nm, which is within the ultraviolet range.
