47-897 15mm Dia. x 15mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-897 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 15mm diameter and a 15mm focal length, making it a versatile choice for various optical applications.
The lens is constructed from n-SF11 Schott, a high-index glass material known for its excellent optical properties. This material, combined with the lens's double-convex geometry, enables the lens to deliver superior performance in terms of light transmission and focus.
The 47-897 features a standard visible coating on both the front and back surfaces. This coating, denoted as 'VIS 0deg', is designed to enhance the lens's performance in the visible light spectrum, specifically between 425 and 675nm. It reduces surface reflections, thereby improving light transmission and enhancing the overall image quality.
The lens has an outer radius of 0mm and an inner radius of 0mm, indicating a uniform curvature across its surface. The edge thickness measures 1.93mm, while the center thickness is 4.5mm, providing a balanced structure that can withstand typical optical application requirements.
