The 48-038 is a 12mm diameter, double-convex lens with a 45mm focal length, sourced from the renowned optical components vendor, Edmund Optics. This lens, designed for use in the ultraviolet (UV) spectrum, is uncoated, offering a clear, unaltered view of the UV light spectrum.
The lens's geometry is characterized by its base shape, which is circular, and its spherical design, featuring two convex surfaces. The first surface has a radius of curvature of 40.79mm, while the second surface has a radius of curvature of -40.79mm. This design results in an effective focal length (EFL) of 45mm and a back focal length (BFL) of 43.96mm. The lens's edge thickness is 2.1mm, while its center thickness is 2.99mm.
The lens is made from fused silica, identified as mal-1965 in the material database. This material is known for its high transparency in the UV spectrum, making it an ideal choice for UV applications. The lens is designed to operate at a wavelength of 587.6nm.
Please note that the lens is uncoated, which means it does not have any anti-reflective or protective coatings. This may result in increased reflection and susceptibility to environmental damage. However, it also means that the lens provides an unaltered view of the UV light spectrum.
