10mm Diameter x 40mm FL NIR I Coated Double-Convex Lens
This is a 10mm diameter, 40mm focal length double-convex lens, coated with NIR I for the spectral range of 600-1050nm. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 587.6nm, making it suitable for a wide range of optical applications.
The double-convex geometry of the lens, with radii of curvature of 40.91mm and -40.91mm, provides a high degree of focusing power. The lens has an edge thickness of 1.89mm and a center thickness of 2.5mm, ensuring structural integrity and durability.
The lens features a standard anti-reflection coating, EDM NIR-I, on both the front and back surfaces. This coating is designed to minimize surface reflections and increase transmission in the near-infrared region, enhancing the overall performance of the lens.
The lens has an effective focal length of 40mm, providing a relatively wide field of view. The back focal length is 39.16mm, which should be considered when designing optical systems involving this lens.
