LB4910-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=500.0 mm ARC 350-700nm

The LB4910-A is a high-quality UV Fused Silica Bi-Convex Lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens boasts a diameter of 2 inches and a focal length of 500.0 mm, making it ideal for a wide range of applications that require precise optical manipulation.

The lens is designed with a Spherical shape, featuring a front and back radius of curvature of 459.4 mm and -459.4 mm respectively. This bi-convex design allows for excellent light transmission and focus, making it suitable for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The lens is constructed from UV Fused Silica, a material known for its exceptional optical properties and durability. It has a high Abbe number, making it less susceptible to chromatic aberration, and a wide transmission range from 350 to 700 nm, ensuring high-fidelity optical transmission across a broad spectrum.

The LB4910-A is coated with a broadband anti-reflection coating (ARC), specifically designed for the wavelength range of 350-700 nm. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating also provides protection against environmental factors, ensuring the longevity and reliability of the lens.

In terms of geometry, the lens has a thickness of 3 mm at the edge and 4.4 mm at the center. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface. The effective focal length (EFL) is 500 mm, and the back focal length (BFL) is 498.5 mm.

The lens is currently in stock and available for immediate purchase from Thorlabs. With its superior optical performance, robust construction, and wide range of applications, the LB4910-A is an excellent choice for any optical system that requires a high-quality bi-convex lens.
