63-692 4 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=12mm MgF2 400-700nm
The 63-692 is a high-quality achromatic doublet lens, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed with a 4 mm diameter and a focal length of 12 mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass, respectively. These materials are chosen for their excellent optical properties, contributing to the lens's high performance. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its transmission capabilities within the 400-700nm spectral range.
The geometry of the lens is carefully crafted, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission and minimal distortion. The lens's edge thickness is 2.39 mm, while the center thickness is 1.8 mm, providing a robust and durable structure.
This lens is a multiplet, meaning it consists of multiple elements, which allows for more complex optical designs and corrections. The curvature of the lens elements is precisely engineered, with radii of 7.35 mm, -5.09 mm, and -14.6 mm, contributing to the lens's high chromatic correction and minimal spherical aberration.
