48-534 15mm Dia. UVFS Aspheric Lens; EFL=15mm; NA=0.5 Uncoated

The 48-534 is a 15mm diameter, uncoated UV Fused Silica Aspheric Lens, available from Edmund Optics. This lens is characterized by its high numerical aperture (NA) of 0.5, making it suitable for applications that require high light-gathering capabilities. The lens is designed with a focal length (EFL) of 15mm, which is ideal for moderate magnification applications.

The lens is made from high-quality UV Fused Silica (syn hpfs7980 corning), a material known for its excellent transparency across a wide range of wavelengths, including the ultraviolet (UV) spectrum. This makes the lens suitable for use in UV applications, such as UV microscopy or UV spectroscopy.

The lens features an aspheric design, which helps to reduce spherical aberration and improve optical performance. The aspheric surface is defined by the coefficients k1, k2, and the radii of curvature r1 and r2. The lens has a center thickness of 7.25mm and an edge thickness of 2.43mm, providing structural rigidity and resistance to deformation.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can also make the lens more cost-effective and suitable for applications where coatings may not be necessary or desirable.
