49-975 20mm Dia. x 60mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 49-975 is a UV-VIS coated Plano-Convex lens, boasting a diameter of 20mm and a focal length of 60mm. This lens, sourced from the reputable vendor Edmund Optics, is designed for use within the UV-VIS spectrum, specifically between 250-700nm.
The lens is constructed from fused silica, a material with the material ID 'fused sil mal-1965'. This material is known for its excellent transparency across a wide range of wavelengths, making it an ideal choice for applications that require high-quality imaging or light transmission.
The lens's geometry is characterized by a thickness of 1.62mm at the edge and 3.5mm at the center. The front surface has a radius of curvature of 27.51mm, while the back surface is flat. The lens's effective focal length (EFL) is 60mm, and the back focal length (BFL) is 57.6mm. The lens's inner and outer radii are both 0mm, indicating a uniform thickness across the lens.
The lens features a standard UV-VIS coating on both the front and back surfaces. This coating, identified as 'edm uv-vis std curve', is designed to enhance the lens's performance within the UV-VIS spectrum by reducing surface reflections and improving transmission.
