45-784 6 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=12mm NIR II 750-1550nm
The 45-784 is a high-quality Achromatic Doublet Lens, boasting a 6 mm diameter and an effective focal length (EFL) of 12 mm, specifically designed for use within the Near-Infrared II (NIR II) spectrum of 750-1550 nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available directly from their website with a valid in-stock status.
The lens is constructed from two distinct materials, N-LAK22 and N-SF6, both from Schott, ensuring excellent optical performance. The front and back surfaces of the lens are coated with Edmund Optics' NIR-II standard curve coating, further enhancing its capabilities within the NIR II spectrum.
The lens geometry is carefully designed, with a thickness of 3.74 mm at the edge, a center thickness of 3.2 mm, and a center thickness 'a' of 1.3 mm. The lens features three radii of curvature: r1 at 6.84 mm, r2 at -5.99 mm, and r3 at -69.82 mm. The inner and outer radii are both zero, indicating a circular shape.
This lens is classified as a Multiplet, a type of lens that combines multiple elements to achieve superior optical performance. The 45-784 is a versatile and high-performing lens, ideal for a wide range of applications within the NIR II spectrum.
