69-445 25.0mm Dia. x 30.0mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 69-445 is a Plano-Convex spherical lens, characterized by its circular base shape and a diameter of 25.0mm. This lens is designed with a long focal length of 30.0mm, making it suitable for a variety of applications that require precise focusing. The lens is fabricated from the high-quality material n-BK7 Schott, ensuring durability and excellent optical performance.

The lens features a significant thickness difference between its edge and center, with the edge being 1.73mm and the center 8.06mm. This asymmetry contributes to the lens's unique optical properties. The effective focal length (EFL) of the lens is 30.0mm, and the radius of curvature (R1) is 15.5mm. The back focal length (BFL) is 24.69mm, and the lens does not have an inner or outer radius.

The 69-445 lens is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed for use with a 633nm wavelength. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for laser applications.
