49-791 25.4 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=38.1mm VIS-NIR 400-1000nm

The 49-791 is a high-quality achromatic doublet lens, boasting a 25.4 mm diameter and an effective focal length (EFL) of 38.1mm. This lens is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.

The lens is composed of two elements, made from N-BAF10 and N-SF6 materials, both sourced from the reputable Schott glass manufacturer. This combination ensures excellent optical performance, minimizing chromatic aberration and delivering sharp, clear images.

The lens features a robust construction, with a thickness of 9.44mm at the edge and 10.5mm at the center. The center thickness can be further adjusted to 3mm, providing flexibility for various optical configurations. The lens also has a high refractive index and low dispersion, making it ideal for a wide range of applications.

The 49-791 lens comes with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, which is applied to both the front and back surfaces. This coating enhances the lens's light transmission capabilities, reduces surface reflections, and increases overall system efficiency.

This lens is available from Edmund Optics and is currently in stock, making it a readily accessible option for your optical system needs. For more information, please refer to the provided weblink.
