67-334 25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=160mm VIS-NIR 400-1000nm
This is a high-quality achromatic doublet lens from Edmund Optics, with a catalog number 67-334. The lens is designed for use in the visible to near-infrared spectrum, specifically for wavelengths between 400 and 1000 nanometers. The lens is part of the multiplets category, featuring a circular base shape and a diameter of 25 millimeters.
The lens has an effective focal length (EFL) of 160 millimeters, making it suitable for a variety of optical applications. The geometry of the lens includes a thickness of 4.33 millimeters at the edge, a center thickness of 3 millimeters, and a center thickness 'a' of 2.5 millimeters. The lens's inner and outer radii are 0, indicating a simple, two-element design.
The lens is made from two types of glass: N-BK7 from Schott and N-SF5 from Schott. These materials are chosen for their excellent optical properties and ability to minimize chromatic aberration. The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces to enhance transmission and protect the lens from environmental damage.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
