45-264 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=36mm MgF2 400-700nm
The 45-264 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a 9 mm diameter and a focal length of 36 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 known for their excellent optical properties, contributing to the lens' high performance. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its transmission capabilities within the 400-700 nm spectral range.
The lens' geometry is meticulously designed, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission. The thickness at the edge is 3.32 mm, while the center thickness is 2.5 mm, providing robustness and stability. The lens also features a radius of curvature of 22.16 mm for the first surface and -15.98 mm for the second surface, contributing to its achromatic properties.
