MF-px-50.8-150 50.8 mm Dia. MgF2 Plano-Convex Lens; EFL=150mm Uncoated

The MF-px-50.8-150 is a Plano-Convex Spherical Lens with a diameter of 50.8 mm, making it suitable for a wide range of optical applications. This lens is sourced from Alkor Technologies, a reputable vendor known for its high-quality optical components.

The lens features an EFL (Effective Focal Length) of 150mm, which is a crucial factor in determining the lens's magnification power. The EFL is the distance from the lens's center of curvature to the focal point when the lens is focused at infinity. This lens's EFL indicates that it provides a moderate level of magnification, ideal for many optical systems.

The lens is made from Magnesium Fluoride (MgF2), a material known for its excellent optical properties. MgF2 has a high transmission rate across a wide spectrum, including the ultraviolet region, making it an excellent choice for applications that require high light transmission.

The lens's geometry includes a thickness of 2.7mm at the edge and 8.3mm at the center. The inner and outer radii are 0, indicating a Plano-Convex shape, where one side of the lens is flat, and the other side is curved. This shape is often used in optical systems where a moderate level of magnification and a wide field of view are required.

The lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their optical performance by reducing reflections, increasing durability, or adding specific spectral characteristics. However, this lens's uncoated status does not necessarily mean it is inferior; it simply means it does not have these additional treatments.
