PLCX-50.8-249.8-UV 50.8 mm Dia. UVFS Laser Grade Plano-Convex Lens; EFL=500mm Uncoated

The PLCX-50.8-249.8-UV is a Plano-Convex Spherical Lens, sourced from CVI Laser Optics, designed for use in laser applications. This lens boasts a diameter of 50.8 mm and a thickness at the edge of 5.06 mm, with a center thickness of 6.35 mm. The effective focal length (EFL) of this lens is 500 mm, making it suitable for applications requiring a longer focal length.

The lens is made from UVFS material, specifically identified as "UVFS MAL-1965" in the material ID. This material is well-suited for use with a wavelength of 266 nm, making this lens ideal for ultraviolet (UV) laser applications.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance in specific applications, such as reducing reflection or increasing transmission. However, an uncoated lens can offer advantages in certain scenarios, such as simplicity, cost-effectiveness, or specific performance characteristics.

The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case, indicating a Plano-Convex lens. The curvature of the lens is determined by the radius of curvature (R1), which is 249.84 mm for this lens.
