45-889 25mm Dia. x 40mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-889 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 25mm diameter and a focal length of 40mm, making it suitable for a wide range of applications.
The lens is constructed from n-BK7 Schott, a popular optical glass known for its excellent transparency and low dispersion. This material ensures high-quality imaging and minimal chromatic aberration. The lens features a double-convex geometry, with radii of curvature of 40.42mm for both the front and rear surfaces. This geometry provides a large numerical aperture, enhancing the lens' light-gathering capability.
The 45-889 lens is coated with edm visnir0sp2002000, a broadband anti-reflection coating designed for the visible and near-infrared spectrum (400-1000nm). This coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens.
The lens has a thickness of 1.34mm at the edge and 5.3mm at the center. The back focal length is 38.21mm, and the inner and outer radii are 0mm. This lens is currently in stock, ready for immediate shipping.
