KBC013AR.16 6.35 mm Dia. x -6.3 mm FL; NIR coated; Double-Concave Lens 650-1000nm

The KBC013AR.16 is a high-quality double-concave lens, designed with a spherical shape and a circular base. This lens is sourced from the reputable vendor MKS/Newport, and it is currently in stock, ready for immediate use. The lens has a diameter of 6.35 mm and a thickness at the edge of 3.75 mm, while the center thickness measures 2.5 mm. The effective focal length (EFL) of this lens is -6.3 mm, making it a powerful tool for a variety of optical applications.

The lens's curvature is defined by two radii: r1, which is -6.861 mm, and r2, which is 6.861 mm. The back focal length (BFL) is -7.02 mm, and the inner and outer radii are both 0 mm. The lens is made from N-BK7 Schott, a popular material known for its excellent optical properties.

The KBC013AR.16 lens features a New AR-16 coating on both the front and back surfaces. This anti-reflective coating is specifically designed for the near-infrared (NIR) region, covering the wavelength range of 650-1000 nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it an ideal choice for applications that require high-transmission optics.
