45-415 30 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=200mm MgF2 400-700nm

The 45-415 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 30 mm, is designed for use in the spectral range of 400-700 nm, making it suitable for a wide range of optical applications.

The lens is a multiplet, composed of two distinct materials: N-BK7 and N-SF5, both from Schott. This combination is strategically chosen to minimize chromatic aberration, a common issue in optical systems. The geometry of the lens is meticulously designed, with an effective focal length (EFL) of 200 mm, providing the necessary focus for your optical setup.

The lens features a robust construction, with a thickness of 6.15 mm at the edge and 5 mm at the center. The center thickness can be further reduced to 2.5 mm, providing flexibility for your optical design. The inner and outer radii of the lens are 0, indicating a circular shape that can be beneficial in many applications.

The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating is designed to provide high transmission in the visible spectrum, enhancing the performance of your optical system.
