84-218 9.0mm Dia. x 9.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

The 84-218 is a 9.0mm diameter x 9.0mm focal length Plano-Convex lens, specifically designed for use with a 1550nm wavelength. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock.

The lens is made from n-sf11 Schott material, a popular choice for its high refractive index and low dispersion. The geometry of the lens includes a 1.38mm thickness at the edge, increasing to 3mm at the center, and a 9mm effective focal length (EFL). The front surface has a radius of curvature of 7.06mm, resulting in a back focal length of 7.32mm.

Both the front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 1550, a specialized coating designed for laser applications. This coating enhances the lens' performance by reducing reflections and increasing transmission, making it ideal for use in high-power laser systems.

The lens' spherical shape ensures a wide field of view and low distortion, making it suitable for a variety of applications. Its circular base shape adds to its versatility, allowing it to be used in a wide range of optical systems.
