89-219 6mm Dia. x 18mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-219 is a high-quality Double-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a diameter of 6mm and a focal length of 18mm, is designed to deliver superior optical performance.
The lens is crafted from the high-grade material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high homogeneity. This material ensures the lens delivers sharp, clear images with minimal distortion.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, designed for the wavelength range of 500-1100nm, enhances the lens's performance by reducing surface reflections and increasing transmission. The coating ensures optimal light transmission, making this lens ideal for a wide range of applications, including laser systems, imaging systems, and optical metrology.
The lens's geometry is meticulously designed, with an edge thickness of 1.7mm and a center thickness of 2.2mm. The lens's inner and outer radii are 0mm, and the back focal length is 17.26mm. These parameters contribute to the lens's high performance and versatility.
