32-303 6.25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=20mm MgF2 400-700nm

The 32-303 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.

The lens features a 6.25mm diameter and a focal length of 20mm, providing a compact and efficient optical solution. The doublet is composed of two materials, N-BK7 and N-SF5, both from Schott, ensuring high-quality optical performance. The lens is coated with EDM MgF2 standard curve coatings on both the front and back surfaces, further enhancing its performance by reducing reflection and increasing transmission.

The geometry of the lens is carefully designed with a center thickness of 2.7mm, edge thickness of 3mm, and radii of curvature of 12.3mm and -8.71mm for the first and second surfaces, respectively. The lens also features a third surface with a radius of -24.98mm and a center thickness 'a' of 0.9mm. This complex geometry is designed to correct chromatic aberrations, providing sharp and clear images.

The lens is available for purchase directly from the Edmund Optics website, where it is listed as being in stock.
