45-414 25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=275mm MgF2 400-700nm
The 45-414 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 25 mm diameter, is designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens is a multiplet, featuring a complex geometry that includes three radii (r1, r2, and r3) and two distinct material types. The first material is N-BK7, a high-quality borosilicate crown glass, while the second is N-SF5, a dense flint glass. This combination helps to correct chromatic aberrations, ensuring sharp and clear imaging.
The lens has an effective focal length (EFL) of 275mm, providing a moderate magnification. The edge thickness of the lens is 6.82mm, while the center thickness is 5mm, with an 'a' value of 2.5mm. The lens is coated with EDM MgF2 std curve on both the front and back surfaces, enhancing its transmission capabilities and overall performance.
