KBC037AR.18 25.4 mm Dia. x -100 mm FL; IR coated; Double-Concave Lens 1000-1550nm
The KBC037AR.18 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens, with a diameter of 25.4 mm, is specifically engineered for use within the infrared spectrum, between 1000 and 1550 nanometers.
The lens features a base shape of a circle, with a thickness at the edge of 3.76 mm and a center thickness of 2.5 mm. The effective focal length (EFL) is -100 mm, making it a powerful tool for focusing and diverging light in various applications. The front and back radii of the lens are -103.785 mm and 103.785 mm, respectively, contributing to its double-concave design.
The KBC037AR.18 is crafted from N-BK7 Schott, a popular material in optical systems due to its excellent optical properties and versatility. The lens is coated with a new AR-18 coating on both the front and back surfaces, enhancing its performance in the infrared spectrum by reducing reflection and increasing transmission.
