63-712 12.5 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=15mm VIS 0° 425-675nm
The 63-712 is a high-quality achromatic doublet lens, boasting a 12.5 mm diameter and an effective focal length (EFL) of 15mm, specifically designed for the visible light spectrum ranging from 425 to 675nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website.
The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, which are carefully selected and arranged to minimize chromatic aberration, a common issue in optical systems. The geometry of the lens is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 6mm, ensuring optimal performance.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances the lens's durability and performance in the visible light spectrum. The lens also has a edge thickness of 4.27mm, providing robustness and resistance to external stressors.
