49-340-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm

The 49-340-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, with a wavelength range of 400-1000nm. The achromatic design ensures minimal chromatic aberration, making it ideal for applications requiring high-resolution imaging or precise focus.

The lens features a focal length (EFL) of 30mm, providing a moderate magnification and field of view. The geometry of the lens includes a thickness of 6.55mm at the edge and 6.91mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The lens's design includes two surfaces, both coated with Edmund Optics' VIS-NIR coating (EDM VisNIR 0SP2002000), ensuring high transmission and durability across the specified wavelength range.

The lens is composed of two materials: N-BAF10 and N-SF10, both from Schott. These materials are chosen for their excellent optical properties, including high refractive index and low dispersion, which contribute to the lens's high performance. The lens's base shape is circular, and it is classified as a multiplet due to its composition of multiple elements.

The 49-340-INK is currently in stock and available for purchase through the Edmund Optics website. With its high-quality construction, advanced coating, and wide wavelength range, this lens is a versatile and reliable choice for a variety of optical applications.
