Si-px-50.8-500 50.8 mm Dia. Silicon Plano-Convex Lens; EFL=500mm Uncoated

This is a Si-px-50.8-500 50.8 mm Dia. Silicon Plano-Convex Lens, sourced from Alkor Technologies. The lens has a plano-convex design, which means one side is flat (plano) and the other side is curved (convex). This design is often used to focus or collimate light in various optical systems.

The lens has a diameter of 50.8 mm and a thickness at the edge of 2.5 mm, while the thickness at the center is 2.8 mm. The effective focal length (EFL) of this lens is 500 mm, which is the distance from the lens center to the focal point where light rays converge or diverge.

The lens is made of silicon, specifically silicon sal vil 1957, and is designed to work with a wavelength of 10600 nm. The lens shape is spherical, meaning it has the shape of a sphere. The inner and outer radii are both 0, indicating a symmetrical curvature from the center of the lens.

The lens does not come with any coating, as indicated by the empty 'coating' field in the item data. Coatings are often applied to lenses to reduce reflection, increase transmission, or protect the lens surface. However, this lens is uncoated, which may be suitable for certain applications where such coatings are not required or desired.
