45-788 6 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=30mm NIR II 750-1550nm
The 45-788 is a high-quality achromatic doublet lens, boasting a 6 mm diameter and an effective focal length of 30mm, specifically designed for use within the Near-Infrared II (NIR II) spectrum of 750-1550nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase directly from their website.
The lens is constructed from two distinct materials, N-LAK22 and N-SF6, both from Schott, which contribute to its impressive optical performance. The lens features a sophisticated geometry, with an inner radius and outer radius of 0, a thickness edge of 4.01mm, and a center thickness of 3mm. The r1 and r2 radii are 16.66mm and -16.18mm, respectively, while the r3 radius is -246.07mm.
The 45-788 lens is equipped with a standard coating on both the front and back surfaces, specifically the EDM NIR-II STD CURVE coating. This coating enhances the lens's performance within the NIR II spectrum, making it an ideal choice for applications that require superior optical precision and clarity in this wavelength range.
