69-353 25.0mm Dia. x 300.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

The 69-353 is a Plano-Convex spherical lens, a type of optical lens featuring one side that is flat and the other side that is curved. This particular model has a diameter of 25.0mm and a focal length of 300.0mm, making it suitable for a wide range of applications. The lens is sourced from Edmund Optics, a leading manufacturer of optical components.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens ideal for use in laser applications at a wavelength of 405nm. The lens features a front and back coating of EDM Las V-Coat 405, a specialized coating designed to enhance the lens's performance in laser applications.

The lens has a thickness of 2.5mm at the edge and 3.0mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 300.0mm, and the back focal length (BFL) is 298.02mm.

The lens is circular in shape, making it compatible with a wide range of optical systems. The information provided is valid and the lens is currently in stock, according to the vendor's website. This lens is a reliable and high-performing option for those in need of a Plano-Convex lens for laser applications at 405nm.
