KBC031AR.18 25.4 mm Dia. x -200 mm FL; IR coated; Double-Concave Lens 1000-1550nm
The KBC031AR.18 is a double-concave lens, specifically designed for use within the infrared spectrum, between 1000-1550nm. This lens, sourced from MKS/Newport, boasts a base shape of a circle and is a spherical lens type. The lens has a diameter of 25.4mm, with a thickness at the edge of 3.13mm and a center thickness of 2.5mm.
The lens has an effective focal length (EFL) of -200mm, making it a powerful tool for focusing or diverging light in various applications. The first radius of curvature (R1) is -207.148mm, while the second radius of curvature (R2) is 207.148mm. The back focal length (BFL) is -200.82mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability.
The KBC031AR.18 lens features a new AR-18 coating on both the front and back surfaces. This anti-reflective coating is specifically designed to reduce surface reflections and increase transmission within the infrared spectrum, enhancing the lens's performance in its intended use.
