14BCV250-05-1 12.7 mm Dia. x -250 mm FL; Uncoated; Double-Concave Lens

The 14BCV250-05-1 is a double-concave spherical lens, sourced from Standa, a reputable vendor in the optical industry. This lens boasts a 12.7 mm diameter and a focal length of -250 mm, making it suitable for applications that require a negative focal length. The lens is fabricated from n-BK7 Schott glass, a popular material known for its excellent optical properties and versatility.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2 mm, while the center thickness is 1.8 mm. Notably, the lens does not have any coatings, which is indicated by the empty "coating" parameter in the item data. This uncoated feature might influence the lens's performance in certain applications, particularly those requiring high transmission or specific surface properties.

The lens's design is intended for use at a wavelength of 546 nm, a common reference wavelength in optical systems. The item data does not specify any additional wavelength-related parameters, such as the Abbe number or dispersion characteristics.
