88-923-INK 50.0mm Dia. x 175.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-923-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, 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, a type of anti-reflective coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 5.48mm at the edge and 9.0mm at the center, with an effective focal length (EFL) of 175.0mm. The radius of curvature for the first surface (R1) is 90.44mm, and the back focal length (BFL) is 169.05mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and durability.
The YAG-BBAR coating on this lens is a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is specifically designed for use in the 500-1100nm range, making it ideal for a wide range of applications, including laser systems, bio-imaging, and machine vision systems.
