DCV0810 25.4 mm Dia. x -500 mm FL; Uncoated; Double-Concave Lens

The DCV0810 is a Double-Concave Spherical Lens, part of Union Optic's extensive catalog of optical elements. This lens, with a diameter of 25.4 mm, is designed for use in a wide range of optical applications. The lens's base shape is circular, and it features a double-concave design, making it suitable for applications that require light convergence.

The lens has a center thickness of 2 mm and an edge thickness of 2.3 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is -500 mm, indicating its concave nature. The first radius of curvature (R1) is -518.64 mm, and the second radius of curvature (R2) is 518.64 mm, demonstrating the lens's symmetrical design.

The back focal length (BFL) of the DCV0810 is -500.7 mm, a critical factor to consider when integrating this lens into an optical system. The lens's inner and outer radii are both 0, indicating a uniform curvature throughout.

The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties and durability. The lens is uncoated, providing a clear, unaltered view of the light passing through it. However, users should note that uncoated lenses may be more susceptible to surface reflections and scattering, which could affect the overall performance of the optical system.

This lens is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use visible light. The lens's spherical shape ensures consistent optical performance across the entire surface of the lens.
