88-865-INK 18.0mm Dia. x 36.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-865-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts an 18.0mm diameter and a focal length of 36.0mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflective coating, is designed to operate within the 500-1100nm wavelength range. It significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance.
The geometry of the lens includes a thickness of 1.25mm at the edge and 3.57mm at the center. The inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 18.62mm, and the back focal length is 33.65mm.
This lens is inked, a process that involves applying a dye or ink to the edge of the lens for identification purposes. The inking process does not affect the optical performance of the lens.
