65-303 2.5mm Dia. x 4.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm

The 65-303 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a 2.5mm diameter, is designed for use in the visible to near-infrared spectrum, specifically between 400 and 1000nm.

The lens has a focal length (FL) of 4.0mm, which is the distance from the lens's center to the point where light rays converge. The edge thickness of the lens is 0.56mm, while the center thickness is 0.8mm, providing a balanced structure for light transmission.

The lens's front and back surfaces are coated with "edm visnir0sp2002000", a coating specifically designed for the visible to near-infrared spectrum. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens surface. The lens's base shape is circular, ensuring consistent light transmission in all directions.

This lens is made from n-lasf9 schott, a high-quality optical material known for its excellent transmission properties in the visible to near-infrared spectrum. The material's refractive index is optimized for this spectrum, making it an ideal choice for applications requiring high-performance lenses.
