69-348 25.0mm Dia. x 60.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-348 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 material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties and durability.
The lens features a V-coat 405nm coating on both the front and back surfaces. This coating enhances the lens's performance in laser applications, particularly at the 405nm wavelength. The 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 lens's 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, according to the vendor's website. The link to the product page is provided for your convenience.
