14PCV40-1-1 25.4 mm Dia. x -40 mm FL; Uncoated; Plano-Concave Lens

The 14PCV40-1-1 is a Plano-Concave Spherical Lens, a type of spherical lens characterized by having at least one surface that is concave, or curved inward. This specific model has a diameter of 25.4 mm and a focal length of -40 mm, making it a high-powered negative lens.

The lens is manufactured by Standa, a reputable vendor in the optical industry, and is available for purchase on their website. The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can make the lens more susceptible to environmental factors such as dust, moisture, and scratches, but it also means that the lens does not introduce any additional chromatic aberration or other optical distortions.

The lens is made of n-BK7 Schott, a common type of optical glass known for its excellent optical properties and high transparency in the visible spectrum. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating that it is a simple plano-concave lens with no additional curvature or complexity in its geometry.

The lens's geometry includes a thickness edge of 6 mm and a thickness center of 1.7 mm. This means that the lens is thinner at its center than at its edge, which is typical for plano-concave lenses. The edge thickness helps to provide structural support for the lens, while the center thickness determines the lens's optical power.

Overall, the 14PCV40-1-1 is a high-quality, uncoated plano-concave lens suitable for a wide range of optical applications. Its simple geometry and high optical power make it a versatile and reliable choice for researchers and engineers in the optical industry.
