The 49-382 is a high-quality achromatic doublet lens, boasting a 40 mm diameter and a focal length of 160mm, specifically designed for the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for immediate purchase from their website.
The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring excellent optical performance. The lens features a sophisticated geometry, with an inner radius of 0 and an outer radius of 0, a thickness edge of 9.48mm, and a center thickness of 8.5mm. The r1, r2, and r3 radii are 98.66mm, -70.73mm, and -205.72mm, respectively, contributing to the lens's superior optical properties.
The 49-382 lens is coated with the EDM VIS-NIR 0SP2002000 coating on both the front and back surfaces, enhancing its performance in the VIS-NIR spectrum. This coating reduces surface reflections and increases transmission, making it ideal for a wide range of applications, including but not limited to, imaging, spectroscopy, and beam shaping.
