The 110-1565E 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 (UV) spectrum at a wavelength of 355 nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens has a diameter of 50.8 mm and a thickness at the edge of 5.7 mm. The center thickness is slightly greater at 6 mm. The effective focal length (EFL) of this lens is 2500 mm, which is the distance from the lens's center to the focal point where light rays converge. The radius of curvature for the curved surface (R1) is 1190.2 mm. The inner and outer radii are both 0, indicating that this lens does not have any concave surfaces.
This lens is made from UVFS MAL-1965, a material specifically designed for use in the UV spectrum. The lens's geometry, combined with its material, makes it suitable for a variety of applications that require the manipulation of UV light.
