L-PCX218 140 mm Dia. Plano-Convex Lens; EFL=230mm Uncoated

The L-PCX218 is a Plano-Convex lens with a diameter of 140 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in a variety of optical systems, offering a focal length of 230 mm and a base shape of circular.

The lens's geometry is characterized by a thickness of 3.5 mm at the edge and 26 mm at the center, making it suitable for applications that require a significant difference between the edge and center thickness. The lens's back focal length (BFL) is 212.9 mm, and it has an effective focal length (EFL) of 230 mm, which is the distance from the lens's center to the focal point.

The L-PCX218 is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum, with a wavelength of 587.6 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or protect the lens surface. However, the absence of a coating in this lens may be desirable for certain applications where specific reflectance properties are required.
