45-104 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm MgF2 400-700nm

The 45-104 is a high-quality achromatic doublet lens, 18 mm in diameter, with a focal length of 40mm, specifically designed for use in the spectral range of 400-700nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and boasts a robust construction using N-BAF10 and N-SF10 Schott glass.

The lens features a multilayer MgF2 coating on both the front and back surfaces, providing superior light transmission and reduced reflection. The front surface coating follows the standard EDMMGF2 curve, while the back surface coating adheres to the same standard. This coating ensures optimal performance and durability, making the lens suitable for a wide range of applications.

The lens geometry is intricately designed with a center thickness of 5.98mm, an edge thickness of 5.84mm, and a central aperture thickness of 1.6mm. The radii of curvature for the three surfaces are R1: 26.97mm, R2: -17.64mm, and R3: -205.03mm. The lens's design and construction ensure minimal chromatic aberration and high-resolution imaging.

The 45-104 is a multiplet lens, meaning it comprises multiple elements to achieve superior optical performance. This lens type is commonly used in applications requiring high-quality imaging, such as microscopy, beam shaping, and optical instrumentation.
