LB4941-C UV Fused Silica Bi-Convex Lens; Dia:1 in; f=100.0 mm ARC 1050-1700nm

The LB4941-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 100.0 mm, making it suitable for a wide range of optical applications.

The lens is made from UV Fused Silica, a material with a high transmission range, particularly in the ultraviolet (UV) and near-infrared (NIR) regions. This makes the LB4941-C an ideal choice for applications that require high-transmission optics in these spectral regions.

The lens features a double-sided anti-reflection coating, specifically designed for the 1050-1700nm wavelength range. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating also enhances the lens's durability and resistance to environmental factors, ensuring long-lasting performance.

The geometry of the lens includes a center thickness of 3.8 mm and an edge thickness of 2 mm. The lens's front and back radii of curvature are 91.4 mm and -91.4 mm, respectively, resulting in a back focal length of 98.7 mm. The lens's shape is spherical, which is a common and versatile lens shape in optical systems.
