69-496 25.0mm Dia. x 35.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 69-496 is a Plano-Convex spherical lens, sourced from Edmund Optics, with a diameter of 25.0mm and a focal length of 35.0mm, specifically designed for use with a 785nm wavelength. This lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance.
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 use in laser systems and imaging applications. The lens has a center thickness of 7.01mm and an edge thickness of 2mm, providing a solid and durable structure.
The 69-496 lens is coated with Edmund Optics' Laser V-Coat 785, which is applied to both the front and back surfaces. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection at the 785nm wavelength.
The lens's geometry also includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The effective focal length (EFL) is 35.0mm, and the back focal length (BFL) is 30.42mm, providing a clear focus point and optimal imaging performance.
