The 48-318 is a 25.0mm diameter Plano-Concave lens with a focal length of -150mm, sourced from the reputable optical components vendor, Edmund Optics. This lens is uncoated and designed for use with UV light, making it an ideal choice for applications that require high transmission in the ultraviolet spectrum.
The lens geometry features a concave surface with a radius of curvature of -68.76mm, resulting in a back focal length of -151.71mm. The edge thickness measures 3.59mm, while the center thickness is 2.5mm, providing a robust and stable platform for optical systems. The lens is made from fused silica, a material with a high transmission range spanning from the UV to the near-infrared region, and is identified as fused sil mal-1965 in the Edmund Optics material catalog.
This lens is designed for use at a wavelength of 587.6nm, making it suitable for a wide range of applications, from spectroscopy and interferometry to imaging and beam shaping. Its uncoated surface ensures high transmission across the UV spectrum but may require additional considerations for applications where stray light or surface reflections could impact performance.
