KPC013 6.35 mm Dia. x -12.5 mm FL; Uncoated; Plano-Concave Lens

The KPC013 is a plano-concave lens with a diameter of 6.35 mm and a focal length of -12.5 mm, making it ideal for applications that require light convergence or divergence. This lens is sourced from MKS/Newport, a reputable vendor known for their high-quality optical components.

The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The base shape of the lens is circular, and it features a planar surface on one side and a concave surface on the other. The thickness at the edge of the lens is 3.17 mm, while the center thickness is 2.5 mm.

The KPC013 is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can suffer from increased reflection, which may affect the performance in high-precision applications.

The lens is designed to work with a wavelength of 589 nm, making it suitable for use with a wide range of visible light sources. Its geometry is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
