88-876-INK 20.0mm Dia. x 80.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-876-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, which is optimized for use within the 500-1100nm range, making it versatile for various applications.
The lens has a thickness of 1.13mm at the edge and 2.35mm at the center, with an effective focal length (EFL) of 80.0mm. The radius of curvature for the first surface (R1) is 41.48mm, and the back focal length (BFL) is 78.45mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The YAG-BBAR coating on the lens enhances its durability and performance. This coating reduces reflection and increases transmission, making the lens suitable for high-power laser applications. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
