49-758 12.7 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=15mm MgF2 400-700nm
The 49-758 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 12.7 mm diameter and a focal length of 15mm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.
The doublet is made from two types of Schott glass, N-BAF10 and N-SF57, which are renowned for their optical properties. The lens is coated with EDM MgF2, a standard coating that provides excellent transmission rates and durability.
The lens geometry is meticulously designed, with an inner radius of 0 and an outer radius of 0, indicating a symmetrical design. The thickness at the edge is 5.72mm, while the center thickness is 6.5mm, providing a robust structure. The lens also features a secondary center thickness of 2mm, which can be useful in certain applications.
This lens is ideal for applications that require a wide spectrum transmission, as it is designed to transmit light in the 400-700nm range. The lens is currently in stock and can be purchased directly from the Edmund Optics website, with the catalog number 49-758.
