25mm Dia. x 300mm FL Visible Light Coated UV Double-Convex Lens
This 25mm Dia. x 300mm FL Visible Light Coated UV Double-Convex Lens, sourced from Edmund Optics, is a high-quality optical component designed for a variety of applications. The lens boasts a diameter of 25mm and a focal length of 300mm, making it suitable for use in systems where a long focal length is required.
The lens is constructed from fused silica, a material known for its excellent optical properties and durability. This material is identified as 'fused sil mal-1965' in the item data, indicating its specific composition and characteristics. The lens features a double-convex shape, with radii of curvature of 274.6mm and -274.6mm for the front and back surfaces, respectively. This shape contributes to the lens's ability to focus light effectively.
The lens's coating is another notable feature. Both the front and back surfaces are coated with a standard visible light coating, specifically 'edm vis-0 std curve'. This coating enhances the lens's performance in the visible light spectrum, improving its light transmission and reducing unwanted reflections.
The lens's geometry includes an edge thickness of 2.52mm and a center thickness of 3.09mm. The back focal length is 298.94mm, and the lens has no inner or outer radius, indicating a uniform thickness across the lens.
