63-695 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=25mm MgF2 400-700nm
The 63-695 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 10 mm diameter, is designed for use in the visible spectrum, specifically between 400-700nm. The lens features a focal length of 25mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass. These materials are chosen for their excellent optical properties, including low dispersion and high transmission in the visible spectrum. The combination of these materials in a doublet configuration helps to correct chromatic aberration, a common issue in optical systems.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the overall performance of the lens. The edge thickness of the lens is 3.76mm, while the center thickness is 3.5mm, providing a robust and durable design.
The 63-695 lens is currently in stock and available for purchase through the Edmund Optics website. With its high-quality materials, advanced coating, and precise design, this lens is an excellent choice for a wide range of optical applications.
