KBX076AR.18 25.4 mm Dia. x 200 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
This is a high-quality Double-Convex Lens, sourced from the renowned optical components manufacturer, MKS/Newport. The lens, identified as KBX076AR.18, is designed for use within the infrared spectrum, specifically between 1000nm and 1550nm, making it ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.
The lens features a diameter of 25.4mm and a focal length of 200mm, providing a substantial depth of field and a wide field of view. The lens is constructed from N-BK7 Schott glass, a material known for its excellent optical properties, including high transparency and low dispersion. This ensures that the lens delivers sharp, clear, and distortion-free images.
The KBX076AR.18 is coated with New AR-18 fromfigure on both the front and back surfaces. This anti-reflective coating enhances the lens' performance by reducing surface reflections, thereby increasing transmission and improving image quality. The coating is specifically designed for use within the infrared spectrum, ensuring optimal performance in its intended application.
The lens geometry is spherical, with a radius of curvature of 206.078mm for both the front and back surfaces. This design provides a smooth, regular curve that minimizes spherical aberration, further enhancing the lens' optical performance. The lens has a center thickness of 3.783mm and an edge thickness of 3mm, providing a robust and durable construction.
