KBC034AR.16 25.4 mm Dia. x -150 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The KBC034AR.16 is a high-quality double-concave lens, designed with a base shape of circle and a sub-type of spherical lens. This lens, sourced from the reputable vendor MKS/Newport, boasts a diameter of 25.4 mm and a center thickness of 2.5 mm, ensuring a compact and efficient design. The edge thickness is 3.34 mm, providing robustness and durability.
The lens has an effective focal length (EFL) of -150 mm, making it suitable for a wide range of applications that require concave lenses. The front and back radii of the lens are -155.466 mm and 155.466 mm respectively, contributing to its double-concave structure. The back focal length (BFL) is -150.82 mm, and the lens does not have any inner or outer radius, indicating a uniform curvature.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and versatility. The lens is coated with New AR-16 fromfigure on both the front and back, enhancing its performance in the near-infrared region (650-1000nm). This coating reduces reflection and increases transmission, making the lens ideal for applications that require high light transmission and low loss.
