48-680 25.0mm Dia. x -35 FL; Uncoated; Plano-Concave Lens
The 48-680 is a 25.0mm diameter Plano-Concave lens with a focal length of -35, sourced from the renowned optical component vendor, Edmund Optics. This lens is uncoated, which means it does not have any additional layers to alter or enhance its optical properties.
The lens's geometry is characterized by a thickness of 6.36mm at the edge and 3.5mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The radius of curvature (R1) is -27.47mm, and the back focal length (BFL) is -36.96mm. The lens is made of n-sf11 Schott material, a high-index glass often used in high-performance optical systems due to its excellent Abbe number and low dispersion.
The lens is designed to operate at a wavelength of 587.6nm, making it suitable for applications that require high precision and accuracy in the yellow-orange part of the visible light spectrum. Its spherical shape ensures minimal optical aberrations, making it an ideal choice for imaging and beam shaping applications.
