48-423 18.0mm Dia. x 18.0mm FL; Uncoated; Plano-Convex Lens

The 48-423 is a Plano-Convex lens with a diameter of 18.0mm and a focal length of 18.0mm, making it a versatile choice for various optical applications. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.

The lens is made of n-sf11 Schott material, a high-index glass often used in high-performance optical systems due to its excellent optical properties. The lens's geometry includes a thickness edge of 1.76mm and a thickness center of 5mm, providing a solid structure for your optical setup.

The lens's base shape is circular, and it features a spherical shape, which is a common choice for many optical applications due to its ease of manufacturing and alignment. The lens's inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.

The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This may be suitable for applications where such coatings are not required or desirable. However, it's important to note that uncoated lenses can suffer from increased reflection and reduced transmission, especially at larger angles of incidence.

The lens's effective focal length (EFL) is 18.0mm, which is the same as its focal length. This indicates a lens with a relatively low power, which can be beneficial in applications where you want to minimize optical aberrations.

The lens's wavelength is 587.6nm, which is in the yellow-green part of the visible spectrum. This wavelength is often used in applications such as fluorescence microscopy and spectroscopy.
