45-092 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=27mm MgF2 400-700nm
The 45-092 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens features a 9mm diameter and a focal length of 27mm, providing a compact yet powerful optical solution. The doublet design is composed of two elements, made from N-BK7 and N-SF5 Schott glass, respectively. This combination helps to minimize chromatic aberration, ensuring sharp and clear imaging.
The lens surfaces are coated with Edmund Optics' standard MgF2 coating, which is applied to both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, further improving its performance.
The geometry of the lens is carefully designed to optimize its optical properties. The edge thickness is 4.26mm, while the center thickness is 3.89mm. The lens also features a curvature radius of 15.36mm on the first surface and -12.01mm on the second surface, with an inner radius of 0mm and an outer radius of 0mm.
