LB4910 UV Fused Silica Bi-Convex Lens; Dia:2 in; f=500.0 mm Uncoated

The LB4910 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 at a focal length of 500.0 mm, making it suitable for a wide range of optical applications.

The lens is made of UV Fused Silica, a material known for its excellent transmission properties across a broad spectrum, including the ultraviolet range. This makes the LB4910 an ideal choice for applications that require high transmission in the UV range.

The lens geometry is spherical, with a radius of curvature of 459.4 mm for both the first and second surfaces. This bi-convex design helps to minimize spherical aberration, ensuring superior image quality. The lens has a central thickness of 4.4 mm and an edge thickness of 3 mm, providing robustness and durability.

The LB4910 is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and uncoated lenses can be advantageous in certain situations due to their lower cost and simpler design.

According to the vendor's website, the LB4910 is currently in stock, indicating its availability for immediate purchase and delivery. This lens, like all products from Thorlabs, is backed by their reputation for quality and reliability, making it a trusted choice for your optical needs.
