88-639 6.0mm Dia. x 9.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-639 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 6mm and a focal length of 9mm, making it a compact yet powerful optical component. The lens is made from n-SF5 Schott, a high-quality material known for its excellent optical properties.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to extend the visible range of the lens, making it suitable for use in wavelengths between 350nm and 700nm. This broad spectral range makes the lens versatile and applicable to a wide range of optical systems.
The geometry of the lens is carefully designed to ensure optimal performance. The edge thickness is 0.95mm, while the center thickness is 1.75mm. The lens's effective focal length (EFL) is 9mm, and its back focal length (BFL) is 7.95mm. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
