63-554 20mm Dia. x 80mm FL; Uncoated; Double-Convex Lens

The 63-554 is a high-quality spherical lens, boasting a double-convex design and a 20mm diameter. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for immediate purchase. The lens's focal length is a generous 80mm, making it suitable for a wide range of optical applications.

The lens is crafted from the esteemed material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high light transmission and low dispersion, making it an ideal choice for many optical systems. The lens's geometry is meticulously designed, with an edge thickness of 2.78mm and a center thickness of 4mm, providing a solid and robust structure.

The lens's base shape is circular, and it features a double-convex design, meaning both surfaces of the lens are convex, or outwardly curved. This design is often used to increase the convergence of light rays, making it ideal for use in imaging systems, beam expanders, and other applications where light must be focused or collimated.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of a lens in certain applications, an uncoated lens can be advantageous in others, such as when minimal reflection is required.

The lens's effective focal length (EFL) is 80mm, and its back focal length (BFL) is 78.67mm. The inner and outer radii are 0mm, indicating a symmetrical lens design. The lens's design wavelength is 587.6nm, a common wavelength used in optical design.
