LB4453-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=500.0 mm ARC 650-1050nm

The LB4453-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 applications that require excellent transparency across a broad spectrum, particularly in the ultraviolet (UV) and near-infrared (NIR) regions (650-1050nm).

The lens boasts a diameter of 1 inch (25.4mm) and a focal length of 500.0mm, providing a large working distance and a wide field of view. The bi-convex shape, characterized by two convex surfaces, offers superior focusing capabilities and minimal spherical aberration. The lens's geometry includes an edge thickness of 2mm and a center thickness of 2.4mm, ensuring robustness and durability.

The LB4453-B is coated with Thorlabs BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection losses and increasing transmission, thereby improving overall system efficiency. The coating is designed to operate effectively across the 650-1050nm wavelength range.
