69-448 25.0mm Dia. x 60.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 69-448 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 60.0mm, making it suitable for applications that require a tight focus or high magnification. The lens is fabricated from the high-quality material n-BK7 Schott, ensuring excellent optical performance and durability.
The lens features a V-coat 633nm coating on both the front and back surfaces, enhancing its performance in laser applications at a wavelength of 633nm. This coating reduces reflection and increases transmission, thereby improving the efficiency and quality of the laser beam.
The geometry of the lens includes a thickness of 2.07mm at the edge and 4.7mm at the center. The effective focal length (EFL) is 60.0mm, and the radius of curvature (R1) is 31.01mm. The back focal length (BFL) is 56.9mm, and both the inner and outer radii are 0mm.
This lens is available from Edmund Optics and is currently in stock, making it an ideal choice for users seeking high-quality, readily available optical components.
