KBX049AR.16 25.4 mm Dia. x 38.1 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm
This KBX049AR.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 7.36 mm, with an effective focal length (EFL) of 38.1 mm. The first radius of curvature (r1) is 38.085 mm, and the second radius of curvature (r2) is -38.085 mm, resulting in a back focal length (BFL) of 35.59 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 coatings 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.
