47-707-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm VIS 0° 425-675nm
The 47-707-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use within the visible light spectrum, spanning from 425 to 675 nanometers. The lens boasts an effective focal length (EFL) of 40mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their high-quality optical properties. The N-BAF10 glass is used for the first element, while the second element is made from N-SF10 glass. This combination helps to correct chromatic aberration, a common issue in optical systems, thereby enhancing the overall image quality.
The lens features a standard curvature coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating is designed to minimize surface reflections and improve light transmission, thereby enhancing the overall performance of the lens.
The lens geometry is characterized by a thickness of 5.84mm at the edge, with a central thickness of 5.98mm. The first radius of curvature (r1) is 26.97mm, while the second radius (r2) is -17.64mm. The third radius (r3) is -205.03mm. The lens does not have an inner or outer radius.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
