KBX055AR.18 25.4 mm Dia. x 62.9 mm FL; IR coated; Double-Convex Lens for IR 1000-1550nm
This is a high-quality Double-Convex Lens, designed and manufactured by MKS/Newport, specifically for use in the infrared spectrum, between 1000nm and 1550nm. The lens, identified as KBX055AR.18, has a diameter of 25.4 mm and a focal length of 62.9 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible and near-infrared regions. The lens geometry includes a thickness of 3 mm at the edge and 5.543 mm at the center, with a back focal length of 61.04 mm. The radii of curvature for the first and second surfaces are 64.057 mm and -64.057 mm, respectively.
The KBX055AR.18 lens features a new AR-18 coating on both the front and back surfaces, designed to reduce reflection and increase transmission in the infrared spectrum. This coating ensures optimal performance and minimal loss of light, making it ideal for use in demanding optical systems.
