32-720 15 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm MgF2 400-700nm
The 32-720 is a high-quality achromatic doublet lens, 15 mm in diameter, with a focal length of 30mm, sourced from Edmund Optics. This lens is designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials in a doublet configuration helps to correct chromatic aberration, ensuring sharp, clear images.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating reduces reflection and increases transmission, enhancing the overall performance of the lens. The edge thickness of the lens is 5.88mm, while the center thickness is 6mm, with an additional 1.5mm at the center a.
The geometry of the lens includes an inner radius of 0mm and an outer radius of 0mm, with radii r1 and r2 at 20.72mm and -13.17mm respectively, and r3 at -128.44mm. This specific configuration contributes to the lens's high performance and versatility.
