84-250 12.0mm Dia. x 84.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
This 84-250 Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a diameter of 12.0mm and a focal length of 84.0mm, specifically designed for use with a 1550nm wavelength. The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent transparency and low auto-fluorescence, making it ideal for laser applications.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This design allows for a wide range of applications, including laser beam shaping and focusing. The lens has a thickness of 2.08mm at the edge and 2.5mm at the center, providing a robust structure while maintaining a low profile.
The lens is coated with Edmund Optics' Laser V-Coat, designed explicitly for 1550nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system. The coating is applied to both the front and back surfaces of the lens.
