13-003 25 mm Dia. S-BAH11/N-SF10 Mounted Achromatic Doublet; EFL=35mm MgF2 400-700nm

This is a 13-003 25 mm Dia. S-BAH11/N-SF10 Mounted Achromatic Doublet, available from Edmund Optics. The lens is characterized by its 25 mm diameter and a focal length of 35mm, making it suitable for a variety of optical applications.

The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 from Schott. The S-BAH11 is a high-index, low-dispersion glass, while the N-SF10 is a high-index, high-dispersion glass. The combination of these two elements in a doublet configuration helps to reduce chromatic aberration, making the lens suitable for use in broadband applications, particularly those in the 400-700nm range.

The lens features a standard MgF2 coating on both the front and back surfaces. This coating helps to reduce reflection and increase transmission, enhancing the overall performance of the lens. The edge thickness of the lens is 9.47mm, while the center thickness is 11mm. The lens also has a small inner radius and a larger outer radius, although these are not specified in the data.

The lens is mounted, making it ready for immediate use in optical systems. The weblink provided in the data indicates that the lens is currently in stock, making it a readily available option for those in need of an achromatic doublet lens.
