45-272 3.0mm Dia. x 12.0mm FL; Plano-Convex Lens Uncoated
The 45-272 is a 3.0mm diameter, 12.0mm focal length Plano-Convex lens, uncoated and sourced from Edmund Optics. This lens is a Spherical Lens of the Sub Type Plano-Convex, with a Circular base shape. The lens's geometry includes a 0.9mm thickness at the edge, increasing slightly to 1.08mm at the center, and an Effective Focal Length (EFL) of 12mm. The lens's radius of curvature (R1) is 6.2mm, and the Back Focal Length (BFL) is 11.29mm.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The wavelength for this lens is 587.6nm. The lens's coating is unspecified, indicating it may be uncoated. Coatings are often applied to lenses to reduce reflection and increase transmission, but uncoated lenses can be useful in certain applications where specific reflectance properties are required.
Please note that the lens's Inner and Outer Radius are both 0, indicating that this lens is a simple Plano-Convex lens without any additional curvature or features on the planar side. This lens is in stock and available for purchase, as indicated by its weblink status.
