69-499 25.0mm Dia. x 85.0mm FL; Plano-Convex Lens Laser V-Coat 785nm

The 69-499 is a Plano-Convex Spherical Lens, a high-quality optical component designed for use in a wide range of applications. This lens, sourced from the renowned vendor Edmund Optics, boasts a diameter of 25.0mm and a focal length of 85.0mm, making it a versatile choice for many optical systems.

The lens is crafted from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high transmittance in the visible and near-infrared regions. This material ensures superior image quality and minimal optical aberrations.

The 69-499 features a V-coat 785nm coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in laser applications at a wavelength of 785nm. It provides high reflectivity, low absorption, and excellent laser damage threshold, making it an ideal choice for laser systems.

The geometry of the lens includes a thickness of 2.48mm at the edge and 4.3mm at the center. The lens's design, coupled with its high-quality materials and coatings, makes it a reliable and efficient optical component.

Please note that the lens's inner and outer radii are both 0, indicating a planar surface on one side and a curved surface on the other. This configuration is typical of Plano-Convex lenses, which are often used to collimate or focus light in various optical systems.
