The 83-979 is a high-quality achromatic doublet lens, boasting a 2 mm diameter and an effective focal length (EFL) of 12 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their official website.
The lens is constructed from two types of Schott glass, N-PSK53A and N-LASF9, which are carefully selected to minimize chromatic aberration, a common issue in optical systems. The lens features a standard curvature coating on both the front and back surfaces, identified as 'edm vis-0 std curve'. This coating enhances the lens's overall light transmission and durability, making it an excellent choice for various applications.
The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 1.91 mm. The first radius of curvature (r1) is 7.2 mm, while the second radius (r2) is -7.2 mm, and the third radius (r3) is -27.8 mm. The center thickness of the lens is 1 mm, and the a center thickness is also 1 mm.
This lens is classified as a multiplet, indicating that it is composed of multiple optical elements. The multiplet design allows for more precise control over optical aberrations, further enhancing the lens's performance. The 83-979 is available in stock, ready to be integrated into your optical system.
