4.5mm Dia. x 9mm FL NIR I Coated Double-Convex Lens for 600-1050nm
Discover the 4.5mm Dia. x 9mm FL NIR I Coated Double-Convex Lens, a high-quality optical component designed for applications within the 600-1050nm near-infrared (NIR) range. Sourced from the renowned vendor Edmund Optics, this lens boasts impressive specifications and features that make it an excellent choice for various optical systems.
The lens is constructed with a Schott N-BK7 glass base material, which is well-known for its excellent optical properties, including low dispersion and high Abbe number. This makes the lens suitable for applications requiring high image quality and minimal chromatic aberration.
The double-convex geometry of the lens features radii of curvature of 8.88mm for both the front and back surfaces, yielding an effective focal length (EFL) of 9mm. The lens has a 4.5mm diameter and a center thickness of 2.38mm, with an edge thickness of 1.8mm, providing a robust and compact design.
The lens features EDM NIR-I standard curve coatings on both the front and back surfaces, optimized for the 600-1050nm NIR range. These coatings enhance the lens's performance by reducing surface reflections and increasing transmission, ultimately improving overall system efficiency.
