KBC085AR.16 50.8 mm Dia. x -75 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The KBC085AR.16 is a high-quality double-concave lens, designed with a base shape of a circle, and a diameter of 50.8 mm. This lens is sourced from the reputable vendor, MKS/Newport. The lens features a significant thickness at the edge, measuring 9.36 mm, and a center thickness of 2.5 mm. The effective focal length (EFL) of this lens is -75 mm, making it a powerful tool for a variety of optical applications.
The KBC085AR.16 is made from N-BK7 Schott, a high-grade optical glass known for its excellent optical properties. The lens's geometry includes a first radius (R1) of -77.943 mm and a second radius (R2) of 77.943 mm, contributing to its double-concave structure. The back focal length (BFL) is -75.82 mm, and both the inner and outer radii are 0 mm.
This lens is coated with New AR-16, a high-performance anti-reflective coating, on both the front and back surfaces. This coating is specifically designed for the near-infrared (NIR) region, covering the wavelength range of 650-1000 nm. This coating significantly reduces surface reflections, enhancing the lens's performance and suitability for various applications.
