This is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as item number 89-222, boasts a 6mm diameter and a focal length of 36mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-grade material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for applications that require high-precision imaging or light manipulation.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission across a broad spectrum, specifically from 500 to 1100nm. This makes the lens particularly suitable for applications involving visible and near-infrared light.
The lens's geometry is another notable feature. It has a center thickness of 2mm and an edge thickness of 1.76mm, providing a robust structure while maintaining a low profile. The lens's inner and outer radii are 0mm, indicating a uniform curvature throughout.
