45-137-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=60mm MgF2 400-700nm
The 45-137-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is a multiplet, composed of two different materials - N-BK7 and N-SF5, both from Schott. This combination is used to correct chromatic aberrations, ensuring high-quality imaging. The lens has an effective focal length (EFL) of 60mm, making it a medium telephoto lens.
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 4.21mm, while the center thickness is 3.5mm. The lens also has a small central thickness of 1.5mm, which can be beneficial in certain applications.
The lens is available for purchase directly from the Edmund Optics website, and at the time of data collection, it was in stock. For more detailed information, including technical drawings and performance data, please refer to the product webpage.
