KBC070AR.18 50.8 mm Dia. x -500 mm FL; IR coated; Double-Concave Lens 1000-1550nm
The KBC070AR.18 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of -500 mm, making it ideal for a wide range of applications within the 1000-1550nm infrared spectrum.
The lens is constructed from Schott's renowned n-BK7 glass, a material known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-concave geometry, with radii of curvature of -517.255 mm and 517.255 mm respectively. This geometry, combined with the lens's thickness at the edge (3.51 mm) and center (2.5 mm), contributes to its superior light-bending capabilities.
The KBC070AR.18 is equipped with a new AR-18 coating on both the front and back surfaces. This anti-reflective coating is specifically designed to minimize surface reflections and increase transmission within the lens's operational wavelength range. The coating ensures that the lens performs optimally, reducing losses and improving the overall efficiency of the optical system.
The lens is currently in stock and available for immediate purchase. For more detailed information, including technical specifications and purchasing options, please refer to the vendor's website at https://www.newport.com/f/ar18-n-bk7-bi-concave-lenses.
