LB4140-C UV Fused Silica Bi-Convex Lens; Dia:2 in; f=150.0 mm ARC 1050-1700nm
The LB4140-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is specifically engineered for use in the ultraviolet (UV) spectrum, with a fused silica base that ensures durability and clarity.
The lens boasts a diameter of 2 inches, providing a substantial surface area for light transmission. It features a focal length of 150.0 mm, making it suitable for a wide range of applications that require precise focusing. The lens's geometry includes an edge thickness of 3 mm and a center thickness of 7.8 mm, contributing to its robust structure and excellent optical performance.
The LB4140-C is coated with a broadband anti-reflection (AR) coating, specifically designed for the 1050-1700nm wavelength range. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance. The lens's shape is spherical, a common and reliable design for optical lenses.
