88-920-INK 50.0mm Dia. x 100.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-920-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 has a front and back coating of YAG-BBAR, which is optimized for the wavelength range of 500-1100nm.
The lens's geometry is characterized by a thickness of 3.55mm at the edge and 10mm at the center. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 93.41mm, and both the inner and outer radii are 0mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's shape is spherical, which is the most common and simplest type of lens.
The YAG-BBAR coating on the lens enhances its durability and performance. This coating reduces reflection and increases transmission, making the lens ideal for use in various applications, including imaging, beam shaping, and focusing.
The lens is inked, indicating that it has been marked or labeled for identification or tracking purposes. This feature does not affect the lens's optical performance but is useful for inventory management and quality control.
