PLCC-25.4-772.6-UV 25.4 mm Dia. UVFS Laser Grade Plano-Concave Lens; EFL=-1500mm Uncoated

This is a PLCC-25.4-772.6-UV, a 25.4 mm diameter Plano-Concave Spherical Lens, specifically designed for UVFS (UV Fused Silica) Laser Grade applications. The lens is manufactured by CVI Laser Optics, a renowned vendor in the optical industry.

The lens features a concave shape with a radius of curvature of -772.6 mm, resulting in an effective focal length (EFL) of -1500 mm. This negative focal length indicates that the lens is a diverging lens, which spreads out light rays, making it suitable for specific applications where beam expansion is required.

The lens is made of UVFS, a high-quality material known for its excellent transparency in the ultraviolet region of the spectrum. This makes the lens ideal for use in UV laser systems, where high transmission and clarity are essential.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses may be more susceptible to environmental factors such as dust and moisture, and may not perform as well in high-intensity light applications.

The lens has a center thickness of 2 mm, providing a good balance between durability and optical performance. It is in stock and available for immediate purchase, as indicated by its valid weblink status.
