62-486 12.5 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-25mm VIS 0° 425-675nm
The 62-486 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor Edmund Optics. This lens boasts a 12.5 mm diameter and a focal length of -25 mm, making it suitable for a wide range of applications. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.
The lens features a sophisticated geometry, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness edge of 5.74 mm. The center thickness is 2 mm, while the center 'a' thickness is 2.55 mm. This specific geometry is designed to optimize the lens's performance in various applications.
The 62-486 lens comes with standard ED coating on both the front and back surfaces. This coating, known as "edm vis-0 std curve", is specifically designed to enhance the lens's performance in the visible light spectrum, between 425 and 675 nm. The coating helps to reduce surface reflections, increase transmission, and improve overall image quality.
The lens is available for purchase directly from the Edmund Optics website, where it is listed as being in stock. The provided weblink leads directly to the product page, ensuring easy access for potential buyers.
