KBC019AR.14 12.7 mm Dia. x -75 mm FL; AR coated; Double-Concave Lens 430-700nm
The KBC019AR.14 is a high-quality double-concave lens, designed with a base shape of a circle and a sub-type of spherical lens. This lens is sourced from the reputable vendor, MKS/Newport, and is available for immediate purchase from their website. The lens has a diameter of 12.7 mm and a center thickness of 2.5 mm, with an edge thickness of 2.92 mm, providing a robust and durable structure.
The lens is designed with a focal length of -75 mm, indicated by its effective focal length (EFL), and a back focal length (BFL) of -75.82 mm. The radii of curvature for this lens are -77.943 mm for the first surface and 77.943 mm for the second surface, contributing to its double-concave design. The lens is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The KBC019AR.14 lens is coated with a new AR-14 coating on both the front and back surfaces, enhancing its performance in the spectral range of 430-700 nm. This anti-reflective coating reduces surface reflections, thereby increasing transmission and improving the overall efficiency of the optical system in which it is used.
