48-979 12mm Dia. x 75mm FL; VIS 0deg Coated; UV Double-Convex Lens VIS 0deg 425-675nm
The 48-979 is a high-quality spherical lens, boasting a 12mm diameter and a focal length of 75mm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock. The lens features a double-convex geometry, with a base shape that is circular, making it suitable for a wide range of optical applications.
The lens's geometry includes a thickness of 2.06mm at the edge and 2.59mm at the center. The effective focal length (EFL) is 75mm, while the back focal length (BFL) is 74.11mm. The radii of curvature for the first and second surfaces are 68.36mm and -68.36mm, respectively. The inner and outer radii are both zero.
The lens is constructed from fused silica, specifically identified as mal-1965 in the material ID. This material is known for its excellent optical properties and durability. The lens is designed to operate at a wavelength of 587.6nm.
The lens features a coating on both the front and back surfaces. The front coating is 'edm vis-0 std curve', while the back coating is also 'edm vis-0 std curve'. These coatings are designed to enhance the lens's performance in the visible light spectrum, specifically within the 425-675nm range.
