63-700 12.5 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=15mm MgF2 400-700nm
The 63-700 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 12.5 mm diameter and a focal length of 15mm. This lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, which are renowned for their excellent optical properties. The lens is coated with EDM MgF2 standard curve coatings on both the front and back surfaces, ensuring high transmission and durability.
The lens geometry is carefully designed with a central thickness of 6mm, an edge thickness of 4.27mm, and a 1mm air gap. The curvature radii are R1 = 9.55mm, R2 = -8.6mm, and R3 = -48.5mm. The lens is a multiplet, meaning it is composed of multiple elements to correct chromatic aberrations and improve image quality.
This lens is ideal for applications that require high-resolution imaging in the 400-700nm spectral range. It is available for purchase directly from the Edmund Optics website, where it is currently in stock. The catalog number for this lens is 63-700, and it can be found at the following link: https://www.edmundoptics.com/p/125mm-dia-x-15mm-fl-mgfsub2sub-coated-achromatic-doublet-lens/18417/.
