69-628 50.0mm Dia. x 50.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
This 69-628 Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a diameter of 50.0mm and a focal length of 50.0mm, specifically designed for use with a wavelength of 1064nm. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the near-infrared region, 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 high level of light convergence, making it suitable for focusing light in various applications. The lens has a thickness of 3mm at the edge and 12mm at the center, providing robustness and stability.
The lens is coated with Edmund Optics' Laser V-Coat 1064, a broadband anti-reflective coating designed for high power laser applications. This coating reduces surface reflections, enhancing the transmission of light through the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
