45-824 9 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=15mm NIR II 750-1550nm

The 45-824 is a high-performance achromatic doublet lens, boasting a 9 mm diameter and a focal length of 15 mm, specifically designed for use in the near-infrared spectrum, spanning from 750 to 1550 nm. This lens is sourced from the esteemed optical vendor, Edmund Optics, and is a multiplet type, ensuring superior image quality and minimal chromatic aberration.

The lens is crafted from two distinct materials, N-LAK22 and N-SF6, both from the reputable Schott glass catalog. These materials are carefully selected for their excellent optical properties in the NIR II range. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, further enhancing its performance in the infrared spectrum.

The geometry of the lens is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a central thickness of 4.2 mm. The edge thickness measures 4.84 mm, while the first and second radii of curvature are 9.68 mm and -7.91 mm, respectively. The third radius of curvature is -39.89 mm, contributing to the lens's achromatic properties.

This lens is a versatile and high-quality option for applications that require superior performance in the NIR II spectrum. Its robust construction, precise geometry, and high-quality materials make it an ideal choice for a wide range of optical systems.
