KPC016 12.7 mm Dia. x -100 mm FL; Uncoated; Plano-Concave Lens

The KPC016 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. This lens has a diameter of 12.7 mm and a base shape of a circle. The lens's thickness at the edge is 2.82 mm, while the thickness at the center is 2.5 mm. The effective focal length (EFL) of this lens is -100 mm, making it a negative or diverging lens.

The lens's first radius of curvature (R1) is -51.68 mm, and the back focal length (BFL) is -101.64 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. This lens is made of N-BK7 Schott, a type of glass commonly used in optical applications due to its excellent optical properties.

The lens is designed to operate at a wavelength of 589 nm. It does not have any coating, which means it is uncoated. This could lead to reflections and reduced transmission, but it also means the lens is more cost-effective and suitable for applications where high transmission is not critical.

The lens's geometry and material make it suitable for various applications, including imaging systems, beam shaping, and beam expansion. However, due to its negative focal length, it cannot be used for focusing light.
