69-513 50.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
This is a 69-513 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 50.0mm and a focal length of 250.0mm, making it suitable for a wide range of applications that require precise focusing of light.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. This material is particularly suitable for use in the visible and near-infrared regions of the spectrum, making the lens ideal for use with a wavelength of 785nm.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This geometry provides a large, flat surface for easy integration into optical systems, while the curved surface focuses light to a point. The lens has a center thickness of 4.94mm and an edge thickness of 2.5mm, providing robustness and durability.
The lens is coated with Edmund Optics Laser V-Coat 785, a broadband anti-reflection coating designed for use with lasers at a wavelength of 785nm. This coating reduces reflection and increases transmission, enhancing the performance of the lens in laser applications.
