KBX184AR.16 50.8 mm Dia. x 1000 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm
This KBX184AR.16 lens, sourced from MKS/Newport, is a Spherical Lens of the Sub Type Spherical Lens (Convex-Convex). Its base shape is Circular, and it boasts a diameter of 50.8 mm. The lens has a thickness edge of 3 mm and a thickness center of 3.625 mm, making it a robust and durable choice. The effective focal length (EFL) is 1000 mm, and the back focal length (BFL) is 998.8 mm, providing a long focal length for various applications.
The lens is made of n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The radius of curvature for the first surface (R1) is 1033.022 mm, while the second surface (R2) has a radius of curvature of -1033.022 mm, indicating a double-convex lens. The inner and outer radii are 0 mm, suggesting a uniform curvature.
The lens is coated with new ar-16 fromfigure on both the front and back, indicating an anti-reflective coating suitable for the Near-Infrared (NIR) spectrum, specifically between 650-1000nm. This coating enhances the lens's performance by reducing unwanted reflections and increasing transmission in the specified wavelength range.
