65-520 12.0mm Dia. x 24.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
This 65-520 Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a diameter of 12.0mm and a focal length of 24.0mm, designed for use with a wavelength of 785nm. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
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 as a focusing or collimating element in laser systems. The lens has a center thickness of 2.8mm and an edge thickness of 1.25mm, providing a robust and durable structure.
The lens is coated with Edmund Optics' Laser V-Coat 785, a broadband anti-reflection coating specifically designed for use with 785nm lasers. 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.
