84-242 12.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

The 84-242 is a Plano-Convex Spherical Lens, 12.0mm in diameter and featuring a 20.0mm focal length. This lens is sourced from Edmund Optics and is designed for use with a 1550nm wavelength, making it suitable for a range of applications in this 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 1550, a specialized coating designed to enhance the lens' performance in laser applications. This coating reduces reflection and increases transmission, improving the efficiency and effectiveness of the lens in its intended use.

The geometry of the lens includes a 1.58mm thickness at the edge and a 3.5mm thickness at the center. The lens has an effective focal length (EFL) of 20mm, a radius of curvature (R1) of 10.34mm, and a back focal length (BFL) of 17.69mm. The lens is circular in shape, with no inner or outer radius specified.
