45-797 12 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=50mm NIR II 750-1550nm

The 45-797 is a high-performance achromatic doublet lens, boasting a 12 mm diameter and an effective focal length of 50mm, specifically designed for use in the near-infrared spectrum (750-1550nm). This lens is sourced from the renowned optical vendor, Edmund Optics, and is a testament to their commitment to quality and innovation.

The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6, which are renowned for their excellent optical properties in the NIR II range. The lens features a sophisticated geometry, with a thickness of 4.8mm at the edge, a central thickness of 3mm, and a central thickness 'a' of 2.5mm. The inner and outer radii are optimized for superior performance, with values of 0 and 0 respectively.

The 45-797 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, ensuring minimal reflectance and superior transmission in the NIR II range. This lens is a multiplet, meaning it is composed of multiple elements, which are carefully arranged to correct chromatic aberrations and deliver sharp, clear images.
