32-502 30 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=150mm MgF2 400-700nm
The 32-502 is a high-quality achromatic doublet lens, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible light spectrum.
The lens features a 30mm diameter and an effective focal length (EFL) of 150mm, providing a substantial working distance and a wide field of view. The achromatic design, which combines two different glass types (N-BK7 and N-SF5), effectively corrects for chromatic aberration, ensuring sharp and clear images across the entire spectral range.
The lens is coated with MgF2, a standard coating that provides excellent transmission and anti-reflection properties. This coating is applied to both the front and back surfaces of the lens, further enhancing its performance and durability.
The geometry of the lens includes a center thickness of 8.1mm, an edge thickness of 8.88mm, and radii of curvature of 91.31mm, -65.57mm, and -195.87mm for the first, second, and third surfaces, respectively. This complex geometry is designed to provide optimal performance and minimize optical aberrations.
