10.0mm Dia. x 25.0mm FL NIR I Coated Plano-Convex Lens by Edmund Optics

This 10.0mm Dia. x 25.0mm FL NIR I Coated Plano-Convex Lens, available from Edmund Optics, is a high-quality optical component designed for use in the near-infrared spectrum. The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.

The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light collection and focusing, making it ideal for a wide range of applications. The lens has a diameter of 10.0mm and a focal length of 25.0mm, resulting in an f-number of 2.5. The edge thickness is 1.99mm, while the center thickness is 3.0mm, providing robustness and durability.

The lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the near-infrared spectrum, specifically between 600nm and 1050nm. It reduces surface reflections, improving transmission and overall system efficiency.

The lens is spherical in shape, meaning it has a constant curvature throughout. This shape is easy to manufacture and provides good image quality, making it a popular choice for many optical systems. The lens' inner and outer radii are 0mm, indicating a sharp transition between the lens and the surrounding air.
