49-587 15mm Dia. UVFS Aspheric Lens; EFL=15mm; NA=0.5 VIS 425-675nm
This is the 49-587 model from Edmund Optics, a 15mm Dia. UVFS Aspheric Lens with an effective focal length (EFL) of 15mm and a numerical aperture (NA) of 0.5, designed for the visible light spectrum between 425-675nm.
The lens is made of high-quality UV fused silica (HPFS7980 Corning) and features a circular base shape. It has a diameter of 15mm, with a thickness at the edge of 2.43mm and a center thickness of 7.25mm. The lens's inner and outer radii are not specified, indicating a potentially complex aspheric design.
The lens's geometry includes a front surface with a radius of curvature (R1) of 6.877mm and a back surface (R2) that is flat. The back focal length (BFL) is 10.029mm. The lens's front surface is coated with a visible light coating (VIS 425-675nm), which is also applied to the back surface.
This lens is ideal for applications that require high-quality imaging and precise light control within the specified wavelength range. Its aspheric design allows for superior image quality and reduced aberrations compared to traditional spherical lenses. The lens's robust UV fused silica material ensures durability and resistance to environmental factors, making it suitable for use in various settings.
