45-418 75 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=300mm MgF2 400-700nm

The 45-418 is a high-quality achromatic doublet lens, boasting a 75 mm diameter and a focal length of 300 mm. This lens is meticulously crafted from two types of glass, N-BK7 and N-SF5, both sourced from the reputable Schott brand. The combination of these materials helps to minimize chromatic aberration, ensuring sharp and clear images across the visible spectrum (400-700 nm).

The lens features a robust design, with a thickness of 13.97 mm at the edge and 13.59 mm at the center. The center thickness can be further adjusted to 6 mm if required, providing flexibility for various optical configurations. The lens's inner and outer radii are optimized for optimal performance, although these specific values are not provided in the data.

The 45-418 lens is coated with MgF2, a standard coating that offers excellent transmission properties in the visible spectrum. This coating is applied to both the front and back surfaces of the lens, further enhancing its optical performance.
