47-738-INK 40 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=80mm VIS 0° 425-675nm

The 47-738-INK is a high-quality achromatic doublet lens, sourced from Edmund Optics, with a diameter of 40 mm and a focal length of 80 mm. This lens is specifically designed for the visible spectrum, covering a wavelength range of 425-675 nm. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.

The lens features a standard curve coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall system efficiency.

The geometry of the lens is meticulously designed, with a central thickness of 12.07 mm and edge thickness of 11.75 mm. The lens's inner and outer radii are 0, indicating a flat surface. The lens's first and second radii of curvature are 53.76 mm and -36.73 mm, respectively, while the third radius of curvature is -435.85 mm. These parameters contribute to the lens's excellent imaging performance.

The lens is available in a multiplet configuration, offering versatility and adaptability for various optical systems. The lens's catalog number is 47-738-INK, and it can be found on the Edmund Optics website, where it is currently in stock.
