The 69-426 is a Plano-Convex Spherical Lens, sourced from the reputable optical vendor, Edmund Optics. This lens boasts a 9.0mm diameter and a 72.0mm focal length, making it suitable for a wide range of optical applications.
The lens is crafted from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers sharp, clear images with minimal chromatic aberration.
The 69-426 features a front and back coating of EDMLAS V-Coat 633, a specialized anti-reflective coating designed for use with 633nm wavelengths. This coating enhances the lens's performance by reducing surface reflections and improving light transmission.
The lens's geometry includes a 1.73mm edge thickness and a 2.0mm center thickness, providing robustness and stability. The inner and outer radii are both 0, indicating a simple, straightforward design that is easy to integrate into optical systems.
