84-264 25.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

The 84-264 is a Plano-Convex spherical lens, a type of optical lens with one side planar and the other side curved, offering a variety of benefits in optical systems. This particular lens, sourced from Edmund Optics, boasts a diameter of 25.0mm and a focal length of 250.0mm, making it suitable for a wide range of applications.

The lens is crafted from the material n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for use in the infrared spectrum, as demonstrated by the lens's specified wavelength of 1550nm.

The 84-264 features a front and back coating of EDM Las V-Coat 1550, a specialized anti-reflective coating designed to minimize surface reflections and improve transmission in the 1550nm wavelength range. This coating enhances the lens's performance in laser applications, reducing losses and improving signal quality.

The lens's geometry includes a thickness of 2.39mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 250.0mm. The radius of curvature (R1) is 129.2mm, and the back focal length (BFL) is also 250.0mm. The lens's base shape is circular, and it has no inner or outer radius.
