69-318 6.0mm Dia. x 36.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-318 is a Plano-Convex spherical lens, sourced from Edmund Optics, boasting a 6.0mm diameter and a focal length of 36.0mm. This lens is designed to work optimally with a 405nm wavelength, making it suitable for various applications, including laser systems.
The lens is crafted from n-BK7 Schott, a high-grade optical glass known for its excellent transparency and homogeneity. This material ensures minimal optical loss and maintains the integrity of the light passing through.
The lens features a front and back coating of EDMLAS V-Coat 405, a specialized anti-reflective coating designed to reduce surface reflections and increase transmission efficiency. This coating is particularly beneficial in laser applications, where maintaining the integrity and direction of the laser beam is crucial.
The geometry of the lens includes a thickness of 1.36mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 36.0mm. The lens's inner and outer radii are 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 18.61mm, and the back focal length (BFL) is 34.95mm.
