14PCV250-05-1 12.7 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens

This is a Plano-Concave Lens from Standa, a renowned vendor in the optical industry. The lens, which has a base shape of a circle, is designed with a spherical geometry, featuring a diameter of 12.7 mm and a thickness that varies from 3.3 mm at the center to 3.5 mm at the edge.

The lens is intended for use with a wavelength of 546 nm and has an effective focal length (EFL) of -250 mm. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a concave surface on the other.

The lens is made of 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 applications due to its superior optical properties.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, in this case, the lens is left uncoated, which may be suitable for certain applications where specific coating characteristics are not required.

The lens is currently in stock and available for immediate purchase. For more information, you can refer to the vendor's website provided in the item data.
