45-439 20.0mm Dia. x 80.0mm FL; Uncoated; Plano-Convex Lens
The 45-439 is a Plano-Convex lens with a diameter of 20.0mm and a focal length of 80.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its diameter, thickness, and radii. The diameter is 20.0mm, and the thickness varies from 1.13mm at the edge to 2.35mm at the center. The curvature of the lens is defined by its radii: the first radius (R1) is 41.48mm, and the back focal length (BFL) is 78.45mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens is designed to work with a wavelength of 587.6nm. Its shape is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance. The lens's coating is listed as '{}', indicating that it is uncoated.
This lens is a great option for applications that require a simple, uncoated Plano-Convex lens. It can be used in various settings, including imaging systems, beam shaping, and other optical systems. Please note that the lack of coating may make the lens more susceptible to environmental factors and may affect its performance in certain applications.
