DCV0803 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens

The DCV0803 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 requiring a negative lens.

The lens has a center thickness of 2 mm and an edge thickness of 4.1 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is -75 mm, indicating its concave nature. The first radius of curvature (R1) is -78.09 mm, and the second radius (R2) is 78.09 mm, demonstrating the lens's symmetric double-concave design. The back focal length (BFL) is -75.7 mm.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is widely used in various optical systems due to its superior optical properties. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, coating options are typically available from the vendor upon request.

This lens is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use this specific wavelength. The lens's shape is spherical, a common design for optical lenses due to its ease of manufacturing and versatility.
