The 47-662 is a high-quality achromatic doublet lens, boasting a 12.5 mm diameter and an effective focal length (EFL) of 25mm. This lens is designed for use within the visible light spectrum, specifically between 425-675nm, making it suitable for a wide range of optical applications.
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's high performance. The lens features a standard curve coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating enhances the lens's durability and light transmission capabilities.
The lens geometry is carefully designed with a thickness of 4.9mm at the edge and 5mm at the center. The center thickness includes an additional 1.25mm 'a' portion. The lens's inner and outer radii are 0, and the first and second radii of curvature are 17.27mm and -10.99mm, respectively. The third radius of curvature is -107.03mm.
