63-765 40 mm Dia. N-BK7/N-SF5 Negative Achromatic Doublet; EFL=-100mm MgF2 400-700nm
The 63-765 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 40 mm diameter, is designed for use in the visible spectrum, specifically optimized for the 400-700 nm range.
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 lens's geometry is meticulously designed, with an effective focal length (EFL) of -100 mm, providing a robust platform for various optical applications.
The lens's front and back surfaces are coated with Edmund Optics' standard MgF2 coating, ensuring high transmission and durability. The edge thickness is 15.08 mm, while the center thickness is 4 mm, providing a robust and stable platform for optical systems. The inner and outer radii are 0, indicating a circular shape, which is beneficial for uniform light distribution.
This lens is available for purchase directly from the Edmund Optics website, and the link provided is valid and indicates the product is in stock, ensuring quick delivery for your optical project needs.
