48-285 25mm Dia. x 75mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 48-285 is a UV Plano-Convex Lens, 25mm in diameter and 75mm focal length, manufactured by Edmund Optics. This lens is designed for use within the UV spectrum, specifically between 250-425nm, and features UV-AR coating on both the front and back surfaces.
The lens geometry includes a 2.08mm edge thickness and a 4.43mm center thickness. The front surface has a radius of curvature of 34.39mm, resulting in a back focal length of 71.96mm. The lens is made from fused silica (mal-1965), ensuring high transmittance and durability.
The UV-AR coating on both surfaces is standard for Edmund Optics and provides excellent anti-reflection properties, further enhancing the lens's performance within the UV spectrum. This lens is ideal for applications requiring high-quality imaging or light transmission within the UV range, such as UV microscopy, spectroscopy, or other UV-based optical systems.
Please note that the lens is spherical, which may cause some optical aberrations, particularly at wider apertures. However, this is common in many optical systems and can often be corrected with additional optical elements or careful system design.
