111-1550E 50.8 mm Dia. x 1000 mm FL; Uncoated; Double-Convex Lens

The 111-1550E is a double-convex lens, characterized by its spherical shape and circular base. This lens, sourced from EKSMA Optics, boasts a diameter of 50.8 mm and a center thickness of 6 mm. The edge thickness is slightly less at 5.3 mm, providing a subtle curvature that contributes to its double-convex design.

The lens has an effective focal length (EFL) of 1000 mm, making it suitable for applications that require substantial magnification or focus. The radii of curvature for the first and second surfaces are 951.2 mm and -951.2 mm, respectively, further emphasizing its double-convex nature.

The lens is crafted from UVFS Mal-1965, a material specifically designed for use in the ultraviolet spectrum at 355 nm. This material choice ensures optimal performance in UV applications, making it a reliable choice for users working in this wavelength range.

Notably, this lens is uncoated, offering a bare, unaltered surface. While coatings can enhance performance by reducing reflection, increasing transmission, or adding other desirable properties, an uncoated lens can be advantageous in certain applications where a natural lens surface is preferred.
