49-308-INK 6.25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm

The 49-308-INK is a high-quality achromatic doublet lens, boasting a 6.25 mm diameter and a focal length of 30mm, specifically designed for the visible to near-infrared spectrum (400-1000nm). This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate use with a valid "in stock" status.

The lens is constructed from two types of materials, N-BK7 and N-SF5, both from Schott, ensuring superior optical performance. The lens features a sophisticated geometry, with an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 2.3mm. The edge thickness is 2.8mm, and the lens has a front and back coating of EDm VISNIR0SP2002000, providing excellent resistance to environmental factors and ensuring longevity.

The 49-308-INK is a multiplet lens, meaning it is composed of multiple elements, in this case, two. This design helps to correct chromatic aberrations, a common issue in optical systems, making the lens ideal for a wide range of applications, including but not limited to, imaging, metrology, and beam shaping.
