49-777 12.7 mm Dia. N-BAK1/N-SF15 Achromatic Doublet; EFL=50.8mm VIS 0° 425-675nm
The 49-777 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a 12.7 mm diameter and a focal length of 50.8mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of materials, N-BAK1 and N-SF15, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces, enhancing its light transmission capabilities and providing protection against environmental factors.
The lens's geometry is carefully crafted, with a thickness of 3.16mm at the edge and 2.5mm at the center. The inner and outer radii are 0mm, and the lens features a center thickness 'a' of 1.5mm. The lens's design includes three radii (r1, r2, and r3) that contribute to its overall optical performance.
This lens is designed for use in the visible light spectrum, specifically between 425nm and 675nm, and has a 0-degree angle of incidence. The lens's web link is valid and in stock, indicating its availability for immediate use.
