KBC019AR.16 12.7 mm Dia. x -75 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The KBC019AR.16 is a high-quality double-concave lens, designed with a base shape of a circle and a sub-type of spherical lens. This lens is sourced from the reputable vendor, MKS/Newport. It boasts a diameter of 12.7 mm and a center thickness of 2.5 mm, with an edge thickness of 2.92 mm, providing a robust structure for various applications.
The lens has an effective focal length (EFL) of -75 mm, making it suitable for use in optical systems that require a negative focal length. The first radius of curvature (R1) is -77.943 mm, while the second radius (R2) is 77.943 mm, indicating a symmetrical design that can help minimize optical aberrations.
The KBC019AR.16 is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. This lens is specifically designed for use in the near-infrared (NIR) region, with a wavelength of 589 nm, making it ideal for applications such as spectroscopy, biomedical imaging, and optical communication systems.
The lens features a New AR-16 coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 650-1000 nm wavelength range, further enhancing its performance in NIR applications.
