63-722 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm VIS-NIR 400-1000nm

The 63-722 is a high-quality achromatic doublet lens, sourced from the renowned optical component vendor, Edmund Optics. This lens is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens is 10mm in diameter, making it suitable for a wide range of applications.

The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott. This combination is used to correct chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points. The use of these materials ensures that the lens provides clear, focused images across the entire spectrum of light it is designed to handle.

The lens has an effective focal length (EFL) of 50mm, which is a common choice for many optical systems due to its versatility. The EFL is the distance from the lens's optical center to the point at which light rays converge. This lens also features a range of radii (r1, r2, r3) and thicknesses (thickness edge, thickness center, thickness center a) that contribute to its overall optical performance.

The lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS and NIR spectrums, reducing reflection and increasing transmission.
