65-435 9 mm Dia. N-LAK14/N-SF66 Achromatic Doublet; EFL=12mm NIR II 750-1550nm
The 65-435 is a high-quality achromatic doublet lens, boasting a 9 mm diameter and a focal length of 12 mm, specifically designed for use within the near-infrared spectrum of 750-1550 nm. This lens is sourced from the esteemed 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-LAK14 and N-SF66, both from the reputable Schott glass manufacturer. This combination ensures superior optical performance and minimal chromatic aberration. The lens features a curvature with three radii (r1, r2, and r3) and a central thickness of 6 mm, with an additional 0.21 mm at the edge. The inner and outer radii are 0, indicating a circular shape.
The 65-435 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, ensuring optimal performance within its specified wavelength range. This coating is part of the lens's standard curve, providing reliable and consistent results.
