DCV0804 25.4 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens

The DCV0804 is a Double-Concave Spherical Lens, part of Union Optic's extensive catalog of optical elements. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications.

The lens has a diameter of 25.4 mm and a thickness at the edge of 3.6 mm, ensuring durability and stability. The center thickness is 2 mm, contributing to its overall compact design. The effective focal length (EFL) of this lens is -100 mm, making it suitable for applications requiring strong negative magnification.

The DCV0804's radii of curvature are -104 mm for the first surface and 104 mm for the second, resulting in a double-concave shape. This design is ideal for use in applications where dispersion control and chromatic aberration correction are critical. The back focal length (BFL) of this lens is -100.7 mm, and it has no inner or outer radius, indicating a uniform curvature.

This lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens is uncoated, providing a clear, unaltered view of the light path but offering less protection against environmental factors compared to coated lenses.

The lens is designed to work with a wavelength of 546.1 nm, a common wavelength used in many optical systems. It is a spherical lens, meaning it has the same curvature in all meridional planes, making it easier to manufacture and align in optical systems.
