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.
The lens is currently in stock and available for immediate purchase. For more information, including pricing and detailed specifications, please refer to the product webpage linked below.
