45-793 12 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=25mm NIR II 750-1550nm

The 45-793 is a high-quality achromatic doublet lens, boasting a 12 mm diameter and an effective focal length of 25 mm, specifically designed for use within the near-infrared spectrum (750-1550 nm). This lens is precision-crafted by Edmund Optics, a renowned vendor known for their exceptional optical components.

The lens features a multiplet design, comprised of two distinct materials: N-LAK22 and N-SF6, both from the Schott catalog. This particular combination allows for superior chromatic correction and minimal spherical aberration, thereby ensuring high-resolution images across the entire NIR-II spectral range.

The 45-793 lens boasts a robust construction, with a thickness of 5.58 mm at the edge and 4.5 mm at the center. The center thickness can be further reduced to 2.5 mm, providing additional flexibility for various optical system configurations. The lens also features a generous inner radius of 0 mm and an outer radius of 0 mm, allowing for seamless integration into a wide range of optical systems.

Both the front and back surfaces of the lens are coated with Edmund Optics' standard NIR-II anti-reflective coating, ensuring optimal transmission and minimal loss of light within the specified spectral range. This lens is currently in stock and available for immediate purchase, with more information and purchasing options available on the Edmund Optics website.
