88-921-INK 50.0mm Dia. x 125.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-921-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 YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission of light over a broad spectrum, in this case, between 500nm and 1100nm.
The lens has a thickness of 4.97mm at the edge and 10mm at the center. The effective focal length (EFL) of the lens is 125.0mm, and the back focal length (BFL) is 118.39mm. The radius of curvature for the first surface (R1) is 64.6mm.
The lens is made from N-BK7 Schott, a common type of optical glass known for its excellent optical properties and high Abbe number. The lens is inked, indicating that it has been marked with a unique identifier for tracking and inventory purposes.
This lens is currently in stock, according to the vendor's website, making it a readily available option for those in need of a Plano-Convex lens with these specifications.
