KPC022AR.18 12.7 mm Dia. x -50 mm FL; IR coated; Plano-Concave Lens 1000-1550nm

The KPC022AR.18 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. It boasts a 12.7 mm diameter and a center thickness of 2.5 mm, with an edge thickness of 3.14 mm. The lens has a focal length of -50 mm and a back focal length of -51.64 mm, making it suitable for a variety of optical applications.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The base shape of the lens is circular, and its geometry is plano-concave, meaning one side is flat while the other is curved inward. The lens does not have any inner or outer radius specified, indicating a uniform curvature.

The KPC022AR.18 is coated with New AR-18 on both the front and back surfaces. This anti-reflective coating is designed to reduce reflection and increase transmission in the 1000-1550nm infrared range, making it ideal for IR applications.
