49-352-INK 25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-352-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400 to 1000 nm. The lens is part of Edmund Optics' extensive catalog, and it is available for purchase directly from their website.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their optical properties. The use of these materials ensures high-quality imaging and minimal chromatic aberration. The lens features an effective focal length (EFL) of 30 mm, making it suitable for a wide range of optical applications.
The geometry of the lens is carefully designed to optimize its performance. The edge thickness is 9.3 mm, while the center thickness is 11.04 mm. The lens also features a front radius (R1) of 21.17 mm and a back radius (R2) of -16.08 mm. The inner and outer radii are both zero, indicating a circular shape.
The lens is coated with Edmund Optics' VIS-NIR0SP2002000 coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the VIS-NIR spectrum, further expanding its range of applications.
