45-959 2.5mm Dia. x 3.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

The 45-959 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by one side being flat and the other side curved. This particular model, sourced from Edmund Optics, boasts a diameter of 2.5mm and a focal length of 3.0mm. The lens is made from the material n-lasf9 schott, a detail often crucial for users seeking components with specific refractive indices or dispersion properties.

The lens features a coating on both the front and back surfaces, specifically the "edm nir-i std curve" coating. This coating is designed to optimize performance within the near-infrared spectrum, specifically between 600 and 1050nm. This makes the lens particularly suitable for applications in fields such as biomedical imaging, spectroscopy, and optical communication, where near-infrared light is often employed.

The lens's geometry includes an edge thickness of 0.47mm and a center thickness of 0.8mm. The effective focal length (EFL) is 3mm, while the back focal length (BFL) is 2.57mm. The inner and outer radii are both 0, indicating a simple, straightforward design that can be easily integrated into various optical systems.

According to the provided item data, this lens is currently in stock and available for purchase, making it a viable option for users seeking immediate solutions for their optical needs.
