45-179-INK 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=200mm MgF2 400-700nm
The 45-179-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 50 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, composed of two different materials, N-BAK4 and N-SF10, both from Schott. This combination is used to correct chromatic aberrations, ensuring high-quality imaging. The lens has an effective focal length (EFL) of 200mm, providing a moderate magnification.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating reduces reflection and increases transmission, enhancing the overall performance of the lens. The edge thickness of the lens is 9.11mm, while the center thickness is 9mm, with a center 'a' thickness of 3.5mm.
The 45-179-INK is currently in stock and available for immediate purchase. For more information, including detailed specifications and pricing, please refer to the Edmund Optics website using the provided weblink.
