47-709-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=60mm VIS 0° 425-675nm
The 47-709-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for visible light applications, with a wavelength range of 425-675nm. The lens boasts an effective focal length (EFL) of 60mm, making it suitable for a wide range of optical systems.
The lens is composed of two elements: N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens' high performance. The lens features a standard anti-reflection coating on both the front and back surfaces, further enhancing its light transmission capabilities.
The lens geometry is carefully designed with a center thickness of 3.85mm and an edge thickness of 4.71mm. The radii of the curvatures are R1 = 42.51mm, R2 = -26.24mm, and R3 = -226.77mm. The lens is shaped as a multiplet, which is a combination of multiple lenses to achieve specific optical properties.
The lens is currently in stock and available for purchase through the Edmund Optics website. For more detailed information, including technical drawings and performance data, please refer to the product page on the Edmund Optics website.
