The 88-886-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 25.0mm and a focal length of 85.0mm, 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 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 the 500-1100nm wavelength range. This makes the lens ideal for use in applications such as laser systems, beam shaping, and imaging systems that operate within this wavelength range.
The lens has a center thickness of 4.3mm and an edge thickness of 2.48mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 85.0mm, and the back focal length (BFL) is 82.17mm. The radius of curvature (R1) is 43.93mm.
