KBX163AR.16 50.8 mm Dia. x 175 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm
This KBX163AR.16 lens, sourced from MKS/Newport, is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 650 and 1000nm. It is a spherical lens, featuring a double-convex geometry, which is known for its ability to focus light effectively.
The lens has a diameter of 50.8mm and a focal length of 175mm, making it suitable for a wide range of applications. The edge thickness is 3mm, while the center thickness is 6.607mm, providing a robust structure that can withstand typical use. The effective focal length (EFL) is also 175mm, and the first and second radii of curvature are 179.757mm and -179.757mm respectively. The back focal length (BFL) is 172.8mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and chemical durability. It is coated with New AR-16 fromfigure on both the front and back surfaces, enhancing its performance in the NIR spectrum by reducing reflection and increasing transmission.
