KPX205AR.18 50.8 mm Dia. x 300 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
This KPX205AR.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 300mm, 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 versatility. The plano-convex geometry, with a curvature radius of 155.04mm, ensures a high level of light concentration, making it ideal for focusing applications. The lens has an edge thickness of 3mm and a center thickness of 5.095mm, providing robustness and durability.
The KPX205AR.18 lens features 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 use.
The item data also provides the Effective Focal Length (EFL) of the lens, which is 296.64mm, and the Back Focal Length (BFL), which is 300mm. The Inner Radius is 0mm, indicating a simple, single-element design.
