32-498 30 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=75mm MgF2 400-700nm

The 32-498 is a high-quality achromatic doublet lens, boasting a 30 mm diameter and a focal length of 75 mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website. The product page indicates that it is currently in stock, ensuring quick delivery for your optical project needs.

The lens is composed of two types of glass, N-SSK8 and N-SF10, both from Schott. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. By combining these materials, the 32-498 achieves superior color correction, making it an ideal choice for a wide range of applications.

The lens features a front and back coating of edm mgf2 std curve. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of your optical system.

The lens geometry is also noteworthy. It has a thickness of 8.4 mm at the edge and center, with inner and outer radii of 0 mm. The curvature of the lens is defined by the radii r1 (-40.51 mm) and r2 (38.68 mm), and r3 (-922.04 mm) for the multiplet. This specific geometry is designed to provide optimal image quality and field curvature.
