45-251 12.5 mm Dia. N-F2/N-BK7/N-F2 Hastings Achromatic Triplet; EFL=20mm MgF2 400-700nm

The 45-251 is a high-quality Hastings Achromatic Triplet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the visible spectrum, specifically between 400-700nm.

The lens features a focal length (EFL) of 20mm, making it suitable for applications that require a compact, high-performance optical component. The lens is constructed from three elements, made from N-F2 and N-BK7 Schott glass, which are known for their excellent optical properties.

The geometry of the lens is meticulously designed, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission and minimal distortion. The lens has a thickness of 7.44mm at the edge, 1.1mm at the center, and 7.98mm and 1.1mm at the two center points (a and b).

The lens is coated with EDM MgF2 std curve on both the front and back surfaces, enhancing its light transmission capabilities and providing protection against environmental factors. This lens is a multiplet, meaning it consists of multiple elements, which are carefully arranged to correct chromatic aberrations and provide superior image quality.
