The KBC040AR.16 is a high-quality double-concave lens, designed with a base shape of a circle and a diameter of 25.4 mm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The lens features a significant focal length of -75 mm, making it suitable for a wide range of applications.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The geometry of the lens includes a thickness edge of 4.19 mm and a thickness center of 2.5 mm. The lens's effective focal length (EFL) is -75 mm, and the back focal length (BFL) is -75.82 mm. The radii of the curvature are -77.943 mm for the first surface and 77.943 mm for the second surface.
The KBC040AR.16 lens comes with 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 ideal for use in NIR applications.
