88-868-INK 20.0mm Dia. x 20.0mm FL; Inked; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-868-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 20.0mm and a focal length of 20.0mm, making it a compact and efficient optical component. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance across a wide spectrum.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflection, is designed to reduce surface reflections and increase transmission in the spectral range of 500-1100nm. This makes the lens particularly suitable for applications that require high transmission in the near-infrared region, such as biomedical imaging, laser systems, and optical communication.
The lens has a center thickness of 4.6mm and an edge thickness of 1mm, providing a good balance between mechanical strength and optical performance. The inner and outer radii are 0mm, indicating a sharp transition between the lens and the surrounding medium. The lens's shape is spherical, with a front radius of curvature of 15.7mm and a back focal length of 17.42mm.
