DCV0805 25.4 mm Dia. x -125 mm FL; Uncoated; Double-Concave Lens

The DCV0805 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 use in complex optical systems.

The lens has a center thickness of 2 mm and an edge thickness of 3.2 mm, providing a robust and durable structure. The effective focal length (EFL) of this lens is -125 mm, indicating its concave nature. The first radius of curvature (R1) is -129.92 mm, and the second radius (R2) is 129.92 mm, demonstrating the symmetric double-concave design. The back focal length (BFL) is -125.7 mm.

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 be aware that uncoated lenses may be more susceptible to surface reflections and scattering, which could affect the overall performance of the optical system.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a wide range of applications, from scientific research to industrial inspection. The lens's spherical shape ensures a high level of light concentration, making it ideal for use in systems where light gathering and focusing are crucial.
