LB4972 UV Fused Silica Bi-Convex Lens; Dia:2 in; f=250.0 mm Uncoated

The LB4972 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 2 inches, is designed for use in a wide range of applications due to its superior optical properties and robust construction.

The lens is spherical in shape, featuring a bi-convex design with radii of curvature of 229.1 mm for both the front and rear surfaces. This design results in an effective focal length of 250.0 mm, making it suitable for applications that require a long focal length. The lens has a clear aperture of 2 inches, providing a wide field of view and high light gathering capability.

The lens is made of UV fused silica, a material known for its excellent optical properties, including high transparency across a wide spectrum from UV to near-IR regions. This makes the lens ideal for use in applications that require high transmission, such as laser systems, imaging systems, and spectroscopy.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses at the air-glass interfaces, it also means that the lens is less susceptible to damage from environmental factors, making it suitable for use in harsh environments.

According to the vendor's website, the lens is in stock, indicating its availability for immediate shipping. The website also provides detailed specifications and technical data for the lens, allowing users to make informed decisions when selecting optical components for their applications.
