84-124 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=3mm VIS 0° 425-675nm
The 84-124 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 2 mm diameter and a focal length of 3 mm. This lens is specifically engineered for the visible light spectrum, spanning from 425 to 675 nm, making it an ideal choice for applications that require precise optical performance within this range.
The lens is constructed from two types of Schott glass, N-PSK53A and N-LASF9, which are renowned for their excellent optical properties. The use of these materials ensures minimal chromatic aberration, high transmittance, and excellent image quality. The lens features a standard anti-reflection coating, denoted as 'edm vis-0 std curve' on both the front and back surfaces, further enhancing its light transmission capabilities and reducing unwanted reflections.
The geometry of the lens is carefully crafted, with an edge thickness of 1.6 mm and a center thickness of 1 mm. The lens curvature is defined by three radii: r1 at 1.68 mm, r2 at -1.68 mm, and r3 at -7.39 mm. These parameters contribute to the lens's overall optical performance, ensuring minimal distortion and high-resolution imaging.
