KBX175AR.16 50.8 mm Dia. x 400 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm
This KBX175AR.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 of the Sub Type Spherical Lens (Convex-Convex), with a base shape of Circular.
The lens has a diameter of 50.8mm and a thickness at the edge of 3mm, while the thickness at the center is 4.565mm. The Effective Focal Length (EFL) is 400mm, and the Radius of Curvature for the first surface (R1) is 412.674mm, while for the second surface (R2) it is -412.674mm. The Back Focal Length (BFL) is 398.49mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens features New AR-16 coating on both the front and back surfaces, designed to reduce reflection and increase transmission in the NIR spectrum. The shape of the lens is Spherical, a common choice for its ease of manufacturing and good optical performance.
