47-709 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=60mm VIS 0° 425-675nm
The 47-709 is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens boasts an effective focal length (EFL) of 60mm, specifically tailored for the visible light spectrum, spanning 425-675nm.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, each chosen for their specific optical properties. The use of these materials ensures the lens's ability to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
The lens features a standard anti-reflection coating, denoted as 'edm vis-0 std curve' on both the front and back surfaces. This coating is designed to reduce surface reflections, thereby increasing transmission and improving overall system performance.
The lens geometry is characterized by a central thickness of 3.85mm, with an edge thickness of 4.71mm. The lens's first and second radii of curvature are 42.51mm and -26.24mm, respectively, while the third radius of curvature is -226.77mm. The lens's inner and outer radii are both zero, indicating a circular shape.
According to the vendor's website, this item is currently in stock, making it readily available for immediate use in various optical applications.
