49-788 12.7 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=38.1mm VIS-NIR 400-1000nm

The 49-788 is a high-quality achromatic doublet lens from Edmund Optics, designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.

The lens features a diameter of 12.7mm and an effective focal length (EFL) of 38.1mm, making it a compact yet powerful option for various applications. The geometry of the lens includes a thickness of 3.92mm at the edge, a center thickness of 3.5mm, and a center thickness 'a' of 1.5mm. The lens's inner and outer radii are 0, suggesting a simple, circular design.

The 49-788 is crafted from two types of Schott glass: N-SSK8 and N-SF56. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with Edmund Optics' VIS-NIR0SP2002000 coating on both the front and back surfaces, further enhancing its capabilities in the VIS-NIR spectrum.
