KPX079AR.18 25.4 mm Dia. x 38.1 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX079AR.18 is a Plano-Convex Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 38.1 mm, making it suitable for a wide range of optical applications.
The lens is fabricated from N-BK7 Schott, a popular optical crown glass due to its excellent homogeneity, low optical dispersion, and high transmittance in the visible and near-infrared regions. The lens's geometry includes an edge thickness of 3 mm and a center thickness of 7.643 mm, contributing to its robust construction.
The KPX079AR.18 features a New AR-18 coating on both the front and back surfaces, enhancing its performance in the infrared spectrum, specifically between 1000nm and 1550nm. This coating reduces reflection and increases transmission, making it ideal for IR applications.
The item data indicates that this lens has an inner radius of 0, suggesting a plano surface on one side and a curved surface on the other. This configuration is common in Plano-Convex lenses, which are often used to collimate or focus light.
