112-1540E 50.8 mm Dia. x -2000 mm FL; Uncoated; Plano-Concave Lens
The 112-1540E is a Plano-Concave Lens with a diameter of 50.8 mm and a focal length of -2000 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens's geometry includes a 6 mm thickness at the edge and a slightly reduced thickness of 5.8 mm at the center, providing a subtle curvature.
The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet spectrum at 355 nm. This material choice ensures optimal performance in its intended application. The lens is uncoated, meaning it does not have any additional layers to enhance its durability or alter its optical properties.
This lens is a Spherical Lens, which means it has a surface that is a portion of a sphere. The spherical shape allows for precise control over the light path, making it suitable for various optical applications. The lens's base shape is circular, adding to its versatility in system integration.
