KBC025AR.16 12.7 mm Dia. x -25 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The KBC025AR.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 3.76 mm, providing a robust structure for various applications.
The lens has an effective focal length (EFL) of -25 mm, making it suitable for use in optical systems that require a negative focal length. The first and second radii of curvature are -26.259 mm and 26.259 mm, respectively, contributing to its double-concave design. The back focal length (BFL) is -25.81 mm, and the lens has no inner or outer radius.
The KBC025AR.16 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with New AR-16 fromfigure on both the front and back, enhancing its performance in the near-infrared (NIR) spectrum, specifically between 650-1000nm.
