65-566 1 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=3mm MgF2 400-700nm
The 65-566 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 1mm diameter and a focal length of 3mm. This lens is meticulously crafted from two types of Schott glass, N-PSK53A and N-LASF9, which are renowned for their exceptional optical properties.
The lens geometry is intricately designed with a center thickness of 0.5mm, an edge thickness of 0.91mm, and a curvature that includes radii of 1.75mm, -1.75mm, and -7.13mm. This configuration ensures minimal chromatic aberration and distortion, providing clear, sharp images across the visible spectrum, specifically within the 400-700nm range.
The lens surfaces are coated with Edmund Optics' standard MgF2 coating, which is known for its broadband anti-reflection properties. This coating enhances the lens's light transmission capabilities, reducing unwanted reflections and increasing overall image quality.
The 65-566 is a multiplet lens, meaning it is composed of multiple elements. This design allows for more precise control over the optical properties, resulting in superior image quality. The lens is currently in stock and available for immediate purchase through the Edmund Optics website.
