KPX190AR.18 50.8 mm Dia. x 125 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
This KPX190AR.18 Plano-Convex Lens, sourced from MKS/Newport, is a high-quality optical component designed for use within the infrared spectrum, specifically between 1000nm and 1550nm. The lens boasts a diameter of 50.8mm and a focal length of 125mm, making it suitable for a wide range of applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The plano-convex geometry, with a base shape of circular, features a spherical surface on one side and a flat surface on the other. The radius of curvature for the curved surface is 64.6mm, and the back focal length is 119.59mm. The lens has an edge thickness of 3mm and a center thickness of 8.203mm.
The KPX190AR.18 lens comes with a new AR-18 coating on both the front and back surfaces. This anti-reflective coating is specifically designed to reduce surface reflections and increase transmission within the infrared spectrum, enhancing the lens's performance in its intended application.
Please note that the lens is designed for use in the infrared spectrum and may not perform optimally in other parts of the electromagnetic spectrum. Always ensure that the lens is suitable for your specific application before purchasing.
