KBC070AR.16 50.8 mm Dia. x -500 mm FL; NIR coated; Double-Concave Lens 650-1000nm

The KBC070AR.16 is a high-quality double-concave lens, boasting a diameter of 50.8 mm and a focal length of -500 mm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 650 and 1000nm, making it suitable for a wide range of applications within this wavelength range.

The lens is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and versatility. This is further enhanced by the lens's double-concave geometry, which is designed to converge light rays to a single point. The lens's inner radius is 0, while the outer radius is also 0, indicating a symmetrical design.

The KBC070AR.16 features a New AR-16 coating on both the front and back surfaces. This anti-reflective coating is specifically designed to reduce surface reflections and increase transmission within the NIR spectrum, further optimizing the lens's performance in its intended application range.

The lens has a thickness of 3.51mm at the edge and 2.5mm at the center, providing a robust and durable structure. The back focal length (BFL) is -500.82mm, a value that is crucial for accurate optical system design.
