111-1114E 12.7 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens
The 111-1114E 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 50 mm. The lens is uncoated, making it suitable for applications where coating is not required or preferred.
The lens is a double-convex type, meaning it has two spherical surfaces that curve outwards. The first radius of curvature (r1) is 47.1, while the second radius of curvature (r2) is -47.1, indicating the lens's convex-convex nature. The lens's edge thickness is 2.1 mm, and the center thickness is 3 mm, providing a robust structure for various applications.
The lens is made from UVFS MAL-1965 material, specifically designed for use in the ultraviolet region of the spectrum, with a central wavelength of 355 nm. This makes the lens ideal for applications that require UV transmission, such as UV curing, fluorescence, or analytical instrumentation.
The lens's geometry, including its diameter, thickness, and focal length, makes it suitable for use in compact optical systems where space is limited. The uncoated surface allows for custom coatings to be applied, depending on the specific requirements of the application.
