88-872-INK 20.0mm Dia. x 40.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-872-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 the 500-1100nm range, making it suitable for a wide range of optical applications.
The lens has a thickness of 2.32mm at the edge and 4.9mm at the center, with an effective focal length (EFL) of 40.0mm. The radius of curvature for the first surface (R1) is 20.67mm, and the back focal length (BFL) is 36.77mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.
The YAG-BBAR coating on the lens enhances its durability and performance by reducing surface reflections and increasing transmission. This coating is particularly useful in high-power laser applications, where minimal loss of light and maximum damage threshold are critical.
