49-305-INK 6.25 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=15mm VIS-NIR 400-1000nm

The 49-305-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 6.25 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000nm. The lens is part of the extensive catalog of optical elements available at 3DOptix.

The lens features an effective focal length (EFL) of 15mm, making it suitable for a wide range of optical applications. The achromatic design of the lens helps to minimize chromatic aberration, ensuring sharp and clear images across the entire spectral range. The lens is constructed from two types of glass, N-SSK8 and N-SF10, both from Schott, which are known for their excellent optical properties.

The lens is coated with EDm VIS-NIR 0SP2002000 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and improving transmission, thereby increasing the overall efficiency of the optical system.

The geometry of the lens includes a thickness of 2.64mm at the edge, a center thickness of 2.7mm, and a center thickness 'a' of 0.6mm. The lens's base shape is circular, and it features inner and outer radii of 0mm each. The lens also has two radii of curvature, r1 and r2, measuring 7.95mm and -7.25mm respectively, and a third radius, r3, of -277.83mm.

According to the vendor's website, the lens is currently in stock, making it readily available for immediate use in your optical systems. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
