The 110-1219E is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a base shape of a circle and is designed for use in the ultraviolet spectrum at a wavelength of 355 nm. The lens is uncoated, which means it does not have any additional layers to protect it or alter its optical properties.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3.1 mm. The center thickness is slightly greater at 4 mm. The effective focal length (EFL) of this lens is 200 mm. The radius of curvature for the first surface (R1) is 95.2 mm, while the second surface is flat (Inner Radius: 0, Outer Radius: 0).
This lens is part of the UVFS MAL-1965 material family. According to the vendor's website, this item is currently in stock. For more information, you can refer to the provided weblink.
