62-484 12.5 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-15mm VIS 0° 425-675nm

The 62-484 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 12.5 mm diameter and a focal length of -15mm, making it ideal for applications that require a short focal length and a wide field of view.

The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials ensures high image quality and minimal chromatic aberration, making the lens suitable for a wide range of applications, particularly in the visible spectrum between 425-675nm.

The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances the lens's performance by reducing reflection and improving transmission, thereby increasing the overall efficiency and quality of the optical system.

The lens geometry is also noteworthy, with a thickness of 8.04mm at the edge, 2mm at the center, and 4mm at the center-a. The inner and outer radii are 0, and the curvature radii are -10.62mm, 8.63mm, and 81.12mm for r1, r2, and r3, respectively. This geometry contributes to the lens's excellent optical performance and makes it a versatile choice for various applications.
