KBX073AR.16 25.4 mm Dia. x 175 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm

This KBX073AR.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 25.4 mm. The lens has a thickness edge of 3 mm and a thickness center of 3.896 mm. The Effective Focal Length (EFL) is 175 mm, and the Radius of Curvature (RoC) for the first surface is 180.219 mm, while for the second surface it is -180.219 mm. The Back Focal Length (BFL) is 173.71 mm, and both the Inner and Outer Radius are 0 mm.

The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The wavelength for this lens is 589 nm. The lens features New AR-16 fromfigure coating on both the front and back, designed for the Near-Infrared (NIR) spectrum, specifically for wavelengths between 650 and 1000 nm. This coating enhances the lens's performance in the NIR region by reducing reflection and increasing transmission.
