49-380 40 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=80mm VIS-NIR 400-1000nm

The 49-380 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.

The lens features a 40mm diameter and an effective focal length (EFL) of 80mm, making it suitable for a wide range of optical applications. The lens geometry includes a center thickness of 12.07mm, an edge thickness of 11.75mm, and a range of radii (r1: 53.76mm, r2: -36.73mm, r3: -435.85mm) that contribute to its high-performance optical characteristics.

The 49-380 is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, which is applied to both the front and back surfaces of the lens. This coating is designed to minimize surface reflections and optimize transmission across the entire VIS-NIR spectrum.

In terms of shape, the 49-380 is a multiplet lens, which means it is composed of multiple elements. This design helps to correct chromatic aberrations, a common issue in optical systems, thereby enhancing the overall image quality.
