KBX043AR.18 25.4 mm Dia. x 19.0 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
This is a high-quality Double-Convex Lens, designed and manufactured by MKS/Newport. The lens, identified as KBX043AR.18, is a spherical lens with a base shape of a circle. It has a diameter of 25.4 mm and a thickness at the edge of 3 mm, while the center thickness is 14.725 mm. The effective focal length (EFL) of this lens is 19 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The curvature of the lens is defined by two radii, R1 and R2, which are 16.687 mm and -16.687 mm respectively. The back focal length (BFL) of the lens is 13.28 mm.
The lens is coated with New AR-18, a broadband anti-reflective coating designed for the infrared region, specifically for wavelengths between 1000nm and 1550nm. This coating ensures high transmission and low reflection, enhancing the performance of the lens in its intended application.
The item data indicates that this lens is in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website at https://www.newport.com/f/ar18-n-bk7-bi-convex-lenses.
