38-579-INK 12.5mm Dia. x 15mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-579-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, 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 1.3mm at the edge and 3.1mm at the center, with an effective focal length (EFL) of 15mm. The radius of curvature for the first surface (R1) is 11.77mm, and the back focal length (BFL) is 13.26mm. The lens is made from n-SF11 Schott, a high index glass with excellent transmittance in the visible and near-infrared regions.
The YAG-BBAR coating on the lens is a broadband anti-reflection coating designed for high transmission in the 500-1100nm range. This coating reduces surface reflections and increases the amount of light transmitted through the lens, enhancing the overall performance of the optical system.
