49-763 12.7 mm Dia. N-BAK1/N-SF8 Achromatic Doublet; EFL=44.45mm MgF2 400-700nm
The 49-763 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a base shape of a circular multiplet, offering a wide diameter of 12.7 mm and an effective focal length (EFL) of 44.45 mm.
The lens is meticulously crafted from two types of materials, namely N-BAK1 and N-SF8, both from the reputable Schott glass catalog. This combination ensures superior optical performance and durability.
The lens features a sophisticated coating scheme, with both the front and back surfaces coated with Edmund Optics' standard MgF2 coating, designed for the spectral range of 400-700 nm. This coating enhances the lens's light transmission capabilities and resistance to environmental factors.
The geometry of the lens is intricately designed, with a thickness of 4.04 mm at the edge, 3 mm at the center, and 2 mm at the center a. The inner and outer radii are 0, indicating a simple and efficient design.
