88-861-INK 15.0mm Dia. x 100.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm

The 88-861-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 15.0mm and a focal length of 100.0mm, making it suitable for a variety of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.

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 reduce surface reflections and increase transmission across a broad spectrum, specifically from 500 to 1100nm. This makes the lens ideal for use in applications such as laser systems, imaging systems, and other systems where high transmission and low reflection are required.

The geometry of the lens includes a thickness of 2.45mm at the edge and 3.0mm at the center. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a curved surface on the other. The lens's radius of curvature (R1) is 51.68mm, and its back focal length (BFL) is 98.02mm.

The lens is inked, a process that involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens may be subject to rotation or where maintaining the correct orientation is critical.
