87-599 15.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

The 87-599 is a Plano-Convex spherical lens, a type of optical lens with one side flat and the other side curved outwards, offering a variety of advantages in optical systems. This lens, sourced from Edmund Optics, boasts a diameter of 15.0mm and a focal length of 20.0mm, making it suitable for a wide range of applications.

The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties and chemical resistance. This material is particularly suitable for use in the ultraviolet region, making this lens an ideal choice for applications involving 405nm lasers.

The lens features a front and back coating of EDM Las V-Coat 405, a specialized coating designed to enhance the lens's performance in laser applications. This coating helps to reduce surface reflections, increase transmission, and protect the lens from laser damage, thereby improving the overall efficiency and durability of the optical system.

The lens has a thickness of 1.52mm at the edge and 3.8mm at the center, providing a robust structure while maintaining a low profile. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens. The back focal length (BFL) is 17.74mm, a critical parameter for determining the position of the lens in an optical system.
