49-342-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm

The 49-342-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 over a broad spectrum.

The lens features an effective focal length (EFL) of 40mm, providing a moderate magnification and field of view. The geometry of the lens includes a center thickness of 5.98mm and an edge thickness of 5.84mm, contributing to its robust construction and durability. The lens also features a front and back coating of EDMP VIS-NIR 0SP2002000, which enhances its light transmission capabilities and resistance to environmental factors.

The 49-342-INK is composed of two types of glass, N-BAF10 and N-SF10, both from Schott. These materials were chosen for their excellent optical properties, including high refractive indices and low dispersion, which contribute to the lens's high performance and achromatic design.

This lens is currently in stock and available for purchase through the Edmund Optics website. With its high-quality construction, broad spectral range, and achromatic design, the 49-342-INK is a versatile and reliable choice for a wide range of optical applications.
