63-620 30mm Dia. x 30mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 63-620 is a high-quality double-convex lens, boasting a 30mm diameter and a focal length of 30mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available in stock on their website. The lens is designed for visible light applications, specifically catering to the wavelength of 587.6nm.
The lens is constructed from n-SF11 Schott material, a popular choice for its high refractive index and low dispersion. This material ensures excellent image quality and color correction. The lens features a standard anti-reflective coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances transmission and reduces surface reflections, further improving image quality.
The lens geometry is characterized by its inner and outer radii, both of which are 0mm in this case. The lens has a thickness of 1.43mm at the edge and 6.5mm at the center. The effective focal length (EFL) is 30mm, and the back focal length (BFL) is 28.12mm. The first radius of curvature (R1) is 45.61mm, and the second radius of curvature (R2) is -45.61mm.
