KBC040AR.14 25.4 mm Dia. x -75 mm FL; AR coated; Double-Concave Lens 430-700nm
The KBC040AR.14 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens, with a base shape of a circle, is specifically engineered for use within the wavelength range of 430-700nm, making it suitable for a wide range of optical applications.
The lens boasts a diameter of 25.4mm, with a thickness at the edge of 4.19mm and a center thickness of 2.5mm. The effective focal length (EFL) is -75mm, and the radii of curvature for the first and second surfaces are -77.943mm and 77.943mm respectively. The back focal length (BFL) is -75.82mm, and the lens does not have any inner or outer radius.
The KBC040AR.14 lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features an anti-reflective (AR) coating on both the front and back surfaces, identified as 'new ar-14 fromfigure'. This coating enhances the lens' performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
