The 88-789-INK is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a 5.0mm diameter, 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, ensuring high transmission and low reflection across the 500-1100nm wavelength range. This coating enhances the lens's performance in various applications, including imaging, beam shaping, and light collimation.
The lens's geometry includes a thickness of 1.34mm at the edge, gradually increasing to 1.9mm at the center. The effective focal length (EFL) is 7.5mm, and the radius of curvature (R1) is 5.89mm. The back focal length (BFL) is 6.43mm, and the lens does not have any inner or outer radii, indicating a simple, straightforward design.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. This material, combined with the lens's design, provides a high numerical aperture (NA), making it suitable for high-resolution imaging applications.
