LB4910-B UV Fused Silica Bi-Convex Lens; Dia:2 in; f=500.0 mm ARC 650-1050nm
The LB4910-B is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is specifically crafted from UV Fused Silica, a material with a high transmission range, making it ideal for use in UV applications. The lens boasts a diameter of 2 inches and a focal length of 500.0 mm, providing a large working distance and excellent image quality.
The lens's geometry is characterized by its spherical shape, with radii of curvature of 459.4 mm for both the front and back surfaces. This design ensures a wide field of view and minimal distortion. The lens has a central thickness of 4.4 mm and an edge thickness of 3 mm, providing robustness and durability.
The LB4910-B is coated with Thorlabs BBAR coating on both the front and back surfaces, optimized for the 650-1050 nm range. This coating enhances the lens's transmission and reduces reflection, thereby improving overall system performance.
