65-515 9.0mm Dia. x 18.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
This is a 65-515 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 9.0mm and a focal length of 18.0mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a Plano-Convex geometry, which means one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 1.25mm at the edge and 2.41mm at the center. The inner radius is 0, and the outer radius is also 0. The effective focal length (EFL) is 18.0mm, and the back focal length (BFL) is 16.41mm.
The lens is coated with Edmund Optics Laser V-Coat 785nm on both the front and back surfaces. This coating enhances the lens's performance in laser applications, particularly at a wavelength of 785nm.
