63-593 40mm Dia. x 120mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a high-quality double-convex lens from the renowned optical vendor, Edmund Optics. The lens, identified as the 63-593 model, boasts a diameter of 40mm and a focal length of 120mm, making it a versatile choice for various optical applications.
The lens is crafted from Schott's n-BK7 glass, a material known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens ideal for applications that require high image quality and minimal chromatic aberration.
The lens features a front and back coating of MgF2, a material known for its superior anti-reflective properties. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image contrast. The MgF2 coating is standard and has a curve that is specifically designed by Edmund Optics, ensuring optimal performance across the visible spectrum, particularly between 400-700nm.
The lens's geometry is another notable feature. It has an edge thickness of 3.72mm and a center thickness of 7mm, providing robustness and durability. The lens's inner and outer radii are 0mm, indicating a uniform curvature throughout. The back focal length (BFL) is 117.67mm, and the effective focal length (EFL) is 120mm, which are crucial specifications for accurate optical system design.
