48-425-INK 18.0mm Dia. x 18.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 48-425-INK, boasts a diameter of 18.0mm and a focal length of 18.0mm, making it a versatile choice for various optical applications.

The lens is constructed from Schott's n-SF11 material, a popular choice for its high refractive index and low dispersion. This material is particularly suitable for applications that require high performance in the visible spectrum, as indicated by the VIS 0° coating on both the front and back surfaces. This coating is standard for Edmund Optics and is designed to provide excellent transmission and durability.

The lens geometry is also noteworthy. It has an edge thickness of 1.76mm and a center thickness of 5.0mm, providing a balance between robustness and optical performance. The lens's inner and outer radii are both 0mm, indicating a purely spherical surface. The front surface has a radius of curvature of 14.13mm, while the back surface has a radius of curvature of 15.2mm. This configuration results in a back focal length of 15.2mm.

The lens is designed to work optimally at a wavelength of 587.6nm, which falls within the visible spectrum. This makes it suitable for applications such as imaging, illumination, and beam manipulation in this spectral range.
