45-174 15 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=25mm MgF2 400-700nm
The 45-174 is a high-quality Achromatic Doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 15 mm and an effective focal length (EFL) of 25 mm, is designed for use in the spectral range of 400-700 nm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, S-BAH11 from Ohara and N-SF10 from Schott, which are renowned for their excellent optical properties. The S-BAH11 is a high-index, low-dispersion glass, while the N-SF10 is a dense, high-index flint glass. The combination of these two elements in an achromatic doublet design effectively corrects chromatic aberration, ensuring sharp, clear images.
The lens features a standard MgF2 coating on both the front and back surfaces, which provides excellent anti-reflection properties across the entire spectral range. The edge thickness of the lens is 6.06 mm, while the center thickness is 6.27 mm, providing robustness and durability.
The 45-174 is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. With its superior optical performance and robust design, the 45-174 is an excellent choice for a wide range of optical applications.
