47-735-INK 20 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm VIS 0° 425-675nm

The 47-735-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 20 mm diameter and an effective focal length (EFL) of 40 mm, specifically designed for the visible spectrum range of 425-675 nm.

The lens is meticulously crafted from two distinct materials, N-BAF10 and N-SF10, both from Schott. These materials are known for their exceptional optical properties, contributing to the lens's overall performance. The lens features a standard curve coating on both the front and back, specifically the EDM VIS-0 std curve, which enhances its light transmission capabilities and resistance to environmental factors.

The lens's geometry is intricately designed, with a thickness of 7.83 mm at the edge, a center thickness of 8 mm, and an inner and outer radius of 0 mm. The lens's first and second radii are 27.63 mm and -17.58 mm, respectively, while the third radius is -171.25 mm. This complex geometry is designed to minimize optical aberrations and deliver sharp, clear images.

The lens is available in a multiplet shape, offering versatility and compatibility with various optical systems. The weblink provided leads to the product page on Edmund Optics' website, where users can find more detailed specifications, pricing, and availability information.
