63-699 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm MgF2 400-700nm
The 63-699 is a high-quality achromatic doublet lens, sourced from the renowned optical component vendor, Edmund Optics. This lens, with a 10 mm diameter, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of optical applications.
The lens features a focal length of 100mm, indicated by its Effective Focal Length (EFL). This EFL, combined with its diameter, allows for a compact and efficient optical system. The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring high-quality optical performance.
The 63-699 lens features a complex geometry, with three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge, center, and center-a. This geometry allows for precise control of the lens's optical properties, enabling the correction of chromatic aberrations and the achievement of high resolution and contrast.
The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, reduces surface reflections, and increases the overall system's efficiency.
