The 45-271 is a high-quality achromatic doublet lens, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm wavelength range, making it suitable for a wide array of optical applications.
The lens features a 50mm diameter and an effective focal length (EFL) of 500mm, providing a substantial working distance for your optical setup. The achromatic design, which combines N-BK7 and N-SF5 glass types, effectively minimizes chromatic aberration, ensuring sharp and clear imaging.
The lens is coated with MgF2, a standard coating that offers excellent transmission properties in the visible spectrum. This coating enhances the lens's light-gathering capabilities, reducing unwanted reflections and improving overall image quality.
The geometry of the lens includes a center thickness of 8mm, with an edge thickness of 10.51mm, providing robustness and durability. The lens's design also includes a 305.74mm radius of curvature for the first surface and a -223.2mm radius for the second surface, with a third surface having a -663.82mm radius.
