The 49-876 is a Plano-Convex Lens with a 9.0mm diameter and a 15.0mm focal length, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, offering a simple, cost-effective solution for various optical applications.
The lens's geometry is characterized by a 1.56mm edge thickness and a 3.0mm center thickness. The base shape is circular, ensuring uniform light distribution. The lens's effective focal length (EFL) is 15.0mm, and the radius of curvature (R1) is 7.75mm. The back focal length (BFL) is 13.02mm, and both the inner and outer radii are 0mm, indicating a plano surface on one side.
The lens is made of N-BK7 Schott glass, a popular material for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in optical systems.
Please note that the lens is uncoated, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors. However, uncoated lenses can be advantageous in applications where cost, simplicity, or specific optical characteristics are priorities.
