88-878-INK 20.0mm Dia. x 150.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-878-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 150.0mm, 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 a broad spectrum, specifically from 500nm to 1100nm. 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 3.0mm and an edge thickness of 2.35mm, providing a robust and durable design. The inner and outer radii are both 0mm, indicating a sharp transition from the flat (plano) surface to the curved (convex) surface. The back focal length (BFL) is 148.02mm, and the effective focal length (EFL) is 150mm.
