The 48-819 is a UV-VIS coated plano-convex lens, boasting a diameter of 12mm and a focal length of 50mm. This lens, sourced from Edmund Optics, is designed for use within the ultraviolet to visible light spectrum, spanning from 250 to 700nm.
The lens is constructed from fused silica, a material with a high transmittance across a wide range of wavelengths, making it ideal for applications that require clarity and precision. The plano-convex geometry, characterized by a flat front surface and a curved back surface, is a common choice for focusing or collimating light.
The 48-819 features a standard UV-VIS coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall image quality. The coating is designed to the standard UV-VIS curve, ensuring consistent performance across the specified wavelength range.
The lens's geometry includes a 2.1mm thickness at the edge and a 2.9mm thickness at the center. The back focal length is 48.01mm, and the radius of curvature of the curved surface is 22.92mm. The lens's clear aperture is defined by its 12mm diameter, and the inner and outer radii are both zero, indicating a uniform thickness across the lens's diameter.
