49-929 15 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=20mm MgF2 400-700nm
This is a high-quality achromatic doublet lens from Edmund Optics, catalog number 49-929. The lens is designed with a base shape of a circle and has a diameter of 15 mm. The edge thickness of the lens is 5.98 mm, while the center thickness is 6.8 mm with an additional 2 mm on the back side. The inner and outer radii of the lens are 0 mm each.
The lens has an effective focal length (EFL) of 20 mm, making it suitable for a wide range of optical applications. The front and back surfaces of the lens are coated with EDM MgF2 standard curve coating, which enhances its light transmission capabilities within the 400-700nm spectrum.
The lens is composed of two types of glass, N-BAF10 and N-SF57, both from Schott. The use of these materials in the doublet design helps to correct chromatic aberration, ensuring high-quality imaging.
