This is a 40mm diameter, 80mm focal length double-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is designed for visible light applications, with a wavelength of 587.6nm, and is coated with a standard curve visible light coating on both the front and back surfaces.
The lens's geometry is characterized by a thickness of 3mm at the edge and 8mm at the center, with a back focal length of 77.32mm. The radii of curvature for the first and second surfaces are 81.3mm and -81.3mm, respectively. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens's coating, edm vis-0 std curve, is designed to enhance its performance in visible light applications, specifically within the 425-675nm range. This coating aids in reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
