KBX061AR.18 25.4 mm Dia. x 88.3 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
This is a high-quality double-convex lens, designed and manufactured by MKS/Newport, a renowned vendor in the optical industry. The lens, identified as KBX061AR.18, is specifically engineered for use within the infrared spectrum, with a wavelength of 589 nm, making it suitable for a wide range of applications that require precise optical performance in the IR region.
The lens features a base shape of a circle, with a diameter of 25.4 mm. It has a thickness of 3 mm at the edge and 4.792 mm at the center. The effective focal length (EFL) of the lens is 88.3 mm, which is a critical parameter for determining the lens's focusing capabilities. The back focal length (BFL) is 86.7 mm, and the radius of curvature for both the first and second surfaces is 90.446 mm, indicating a symmetrical double-convex design.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens's coating is AR-18, which is applied to both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections and increase transmission in the infrared region, specifically between 1000 nm and 1550 nm.
