45-878 12mm Dia. x 72mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-878 is a high-quality double-convex lens, 12mm in diameter and with a focal length of 72mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum (VIS-NIR), specifically catering to the wavelength range of 400-1000nm.
The lens boasts a base shape of a circle and is constructed from the high-grade material, n-BK7 Schott, ensuring excellent optical performance. The front and back surfaces of the lens are coated with the advanced EDM VIS-NIR 0SP 200-2000 coating, providing superior protection and enhancing its performance within the VIS-NIR spectrum.
The geometry of the lens is carefully crafted, with an edge thickness of 2.31mm and a center thickness of 2.8mm. The lens' effective focal length (EFL) is 72mm, and the radii of curvature for the first and second surfaces are 73.97mm and -73.97mm, respectively. The back focal length (BFL) is 71.07mm, and both the inner and outer radii are 0mm, indicating a uniform curvature throughout.
This lens is an ideal choice for applications requiring a robust, high-performing optical component within the VIS-NIR spectrum. With its double-convex design, advanced coating, and high-grade material construction, the 45-878 lens promises reliable and efficient performance, making it a valuable addition to any optical system.
