69-490 12.0mm Dia. x 42.0mm FL; Plano-Convex Lens Laser V-Coat 785nm

The 69-490 is a Plano-Convex spherical lens, sourced from Edmund Optics, with a diameter of 12.0mm and a focal length of 42.0mm, specifically designed for use with a wavelength of 785nm. 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 as a focusing or collimating element in laser systems. The lens has a thickness of 1.85mm at the edge and 2.7mm at the center, providing a solid structure and reliable performance.

The 69-490 is coated with Edmund Optics' Las V-Coat 785, a specialized coating designed for use with 785nm lasers. This coating enhances the lens's performance by reducing reflections and increasing transmission, making it ideal for use in laser applications.

The lens is currently in stock and can be purchased directly from the Edmund Optics website. With its high-quality materials, specialized coating, and precise geometry, the 69-490 is a reliable and versatile choice for any optical system operating at 785nm.
