The 63-557 is a high-quality spherical lens, boasting a double-convex design and a 30mm diameter. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock. The lens's focal length is 60mm, making it suitable for a wide range of optical applications.
The lens is uncoated, which means it does not have any anti-reflective or other surface treatments. This can be advantageous in certain applications where the natural properties of the glass are desired. The lens is made from n-BK7 Schott glass, a common and versatile optical material known for its excellent optical properties.
The lens's geometry is characterized by its diameter, thickness at the edge, and thickness at the center. The edge thickness is 1.26mm, while the center thickness is 5mm. The back focal length (BFL) is 58.33mm, and the effective focal length (EFL) is 60mm. The radii of curvature for the first and second surfaces are 61.15mm and -61.15mm, respectively.
The wavelength for this lens is 587.6nm, which falls within the visible light spectrum. This makes the lens suitable for use in applications involving visible light, such as imaging systems, beam shaping, and light collimation.
