89-221 6mm Dia. x 30mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, identified as item number 89-221, boasts a 6mm diameter and a focal length of 30mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The base shape of the lens is circular, and it features a double-convex geometry, which is ideal for applications requiring a high numerical aperture and a short focal length.
The lens is coated with YAG-BBAR on both the front and back surfaces, enhancing its performance in the 500-1100nm wavelength range. This coating reduces reflection, increases transmission, and improves the lens's overall durability.
The lens's geometry includes a 2mm edge thickness and a 2.3mm center thickness, ensuring structural integrity and minimal distortion. The inner and outer radii are 0, indicating a symmetrical design that further contributes to the lens's high performance.
