KBX163AR.18 50.8 mm Dia. x 175 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
The KBX163AR.18 is a high-quality double-convex lens, designed and manufactured by MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of 175 mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The KBX163AR.18 features a double-convex geometry, with radii of curvature of 179.757 mm for the first surface and -179.757 mm for the second surface. This geometry results in a back focal length of 172.8 mm and an effective focal length of 175 mm. The lens has a central thickness of 6.607 mm and an edge thickness of 3 mm, providing robustness and durability.
This lens is coated with New AR-18, a broadband anti-reflective coating designed for the infrared spectrum, specifically for wavelengths between 1000 nm and 1550 nm. This coating significantly reduces surface reflections, enhancing the lens's performance in IR applications.
The KBX163AR.18 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.newport.com/f/ar18-n-bk7-bi-convex-lenses.
