KBX058AR.18 25.4 mm Dia. x 75.6 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm

This is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. It is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm, making it ideal for applications such as IR imaging, spectroscopy, and other infrared-based technologies.

The lens has a diameter of 25.4mm and a focal length of 75.6mm, 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 and durability.

The lens features a double-convex geometry, with radii of curvature of 77.265mm on both sides. This geometry provides a high level of refraction, making it suitable for use in applications where light must be focused or collimated. The lens has a central thickness of 5.102mm and an edge thickness of 3mm, ensuring structural integrity and minimizing optical distortions.

The lens is coated with a new AR-18 coating on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission in the infrared spectrum, further enhancing the lens's performance in its intended application.
