45-166 30mm Dia. x 75mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

The 45-166 is a double-convex lens with a diameter of 30mm and a focal length of 75mm, sourced from the reputable optical vendor, Edmund Optics. This lens is made from the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties, making it a popular choice for various applications.

The lens features a magnesium fluoride (MgF2) coating on both the front and back surfaces. This coating is standard and provides a wide spectral range of 400-700nm, enhancing the lens's performance in transmitting and refracting light. The MgF2 coating also reduces surface reflections, thereby increasing the lens's efficiency and overall optical quality.

The geometry of the lens is meticulously designed with an inner radius of 0 and an outer radius of 0, indicating a symmetrical structure. The thickness at the edge is 2mm, while the center thickness is 4.96mm, providing a robust and durable construction. The effective focal length (EFL) is 75mm, and the back focal length (BFL) is 73.35mm, offering a long focal length that is ideal for various applications.
