69-444 12.0mm Dia. x 100.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 69-444 is a Plano-Convex Spherical Lens, 12.0mm in diameter and featuring a 100.0mm focal length. This lens is sourced from Edmund Optics and is designed for use with a 633nm wavelength, making it suitable for a range of applications in the visible light spectrum.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for use in laser applications due to its high damage threshold.
The lens features a front and back coating of EDM Las V-Coat 633, a specialized coating designed to enhance the lens's performance in laser applications. This coating reduces reflection and increases transmission, improving the efficiency and effectiveness of the lens in laser systems.
The geometry of the lens includes a 2.15mm thickness at the edge and a 2.5mm thickness at the center. The lens has an effective focal length (EFL) of 100.0mm and a back focal length (BFL) of 98.35mm. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens.
