MF-px-50.8-500 50.8 mm Dia. MgF2 Plano-Convex Lens; EFL=500mm Uncoated

The MF-px-50.8-500 is a 50.8 mm diameter Plano-Convex lens, featuring a Magnesium Fluoride (MgF2) coating. This lens is sourced from Alkor Technologies, a reputable vendor known for their high-quality optical elements. The lens is designed for use with a wavelength of 266 nm, making it suitable for a variety of applications in this range.

The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes an outer radius of 0, indicating a flat surface on one side, and an inner radius of 0, suggesting a curved surface on the other side. The thickness at the edge of the lens is 2.6 mm, while the thickness at the center is 4.2 mm. The Effective Focal Length (EFL) of this lens is 500 mm, providing a long focal length that can be beneficial in many optical systems.

The lens is made from Magnesium Fluoride (MgF2), a material with the ID dod-1984-n-o. This material is known for its excellent optical properties, including a high transmission rate and resistance to environmental factors. However, it's important to note that this particular lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from external influences.

The lens data provided does not specify the type of coating, if any, applied to this lens. Therefore, it's assumed that the lens is uncoated. However, Alkor Technologies offers a variety of coatings for their lenses, so it may be possible to request a coated version of this lens if needed.
