KBC022AR.16 12.7 mm Dia. x -50 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The KBC022AR.16 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens boasts a 12.7 mm diameter and a focal length of -50 mm, making it ideal for applications that require a negative focal length. The lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and versatility.
The lens features a unique double-concave geometry, with radii of curvature of -52.103 mm and 52.103 mm for the front and back surfaces, respectively. This geometry results in a back focal length of -50.81 mm, providing a compact and efficient optical solution. The lens has a central thickness of 2.5 mm and an edge thickness of 3.13 mm, ensuring robustness and durability.
The KBC022AR.16 is coated with New AR-16 fromfigure on both the front and back surfaces. This anti-reflection coating is specifically designed for the near-infrared (NIR) region, covering the wavelength range of 650-1000 nm. The coating significantly reduces surface reflections, improving transmission and enhancing overall system performance.
