32-475 20.0mm Dia. x 100.0mm FL Uncoated; Plano-Convex Lens
The 32-475 is a 20.0mm diameter, 100.0mm focal length Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens, designed for general-purpose use, is a Spherical Lens with a Base Shape of Circular and a Sub Type of Plano-Convex.
The lens's geometry is meticulously crafted, with a thickness edge of 3.32mm and a thickness center of 4.3mm. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 97.13mm, and both the inner and outer radii are 0mm, indicating a uniform curvature.
The lens is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. The wavelength for this lens is 587.6nm.
Notably, this lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in a higher reflectance, it also means the lens is more cost-effective and suitable for applications where such coatings are not required or desirable.
The lens's information, including web links, is valid and indicates that it is currently in stock, ensuring quick delivery for your optical needs.
