The 45-431 is a 4.0mm diameter, 12.0mm focal length Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, with its Spherical shape and Circular base, is an Uncoated component, designed for use in a variety of optical applications.
The lens's geometry is characterized by its 1.19mm edge thickness and 1.52mm center thickness, with an Effective Focal Length (EFL) of 12mm. The Radius of Curvature (R1) is 6.22mm, and the Back Focal Length (BFL) is 11mm. The Inner and Outer Radius are both 0mm, indicating a uniform curvature across the lens surface.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The chosen wavelength for this lens is 587.6nm, a common choice for many optical systems.
Please note that this lens is Uncoated, meaning it does not have any anti-reflective or other surface coatings. This may affect its performance in certain applications, particularly those requiring high transmission or low reflectivity.
