87-933 6mm Dia. x 18mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 355nm
The 87-933 is a laser grade plano-convex lens, boasting a 6mm diameter and a focal length of 18mm, specifically designed for use with a 355nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from fused silica, a material with the material ID of mal-1965, ensuring durability and resistance to thermal shock. The front and back of the lens are coated with EDM LAS V-Coat 355, a specialized coating that enhances laser damage threshold and reduces surface reflections.
The geometry of the lens is meticulously designed, with a center thickness of 2mm and an edge thickness of 1.44mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 18mm, and the back focal length (BFL) is 16.62mm. The radius of curvature (R1) is 8.25mm.
This lens is a spherical lens, meaning it has a single spherical surface. The base shape is circular, ensuring symmetry and uniformity in its optical properties. The lens's shape is ideal for use in a wide range of applications, including laser systems, interferometry, and beam shaping.
