63-698 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm MgF2 400-700nm
This is a high-quality 10 mm diameter achromatic doublet lens, catalog number 63-698, sourced from the renowned optical vendor, Edmund Optics. The lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens is a multiplet, meaning it is composed of multiple optical elements. In this case, it is made up of two different materials: N-BK7 and N-SF5, both from Schott. This combination helps to correct chromatic aberration, a common issue in optical systems, making the lens a reliable choice for achromatic applications.
The lens has an effective focal length (EFL) of 50mm, which is a common choice for many optical systems due to its versatility. The edge thickness of the lens is 3.89mm, while the center thickness is 3mm, providing a robust and durable structure. The inner and outer radii of the lens are 0mm, indicating a symmetrical design.
The lens features MgF2 coatings on both the front and back surfaces. This coating, standard from Edmund Optics, provides excellent transmission characteristics and durability. The coating is applied using a standard curve, ensuring consistent performance across the lens surface.
