The LB4330-A 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 and a focal length of 75.0 mm, making it suitable for a wide range of optical applications.
The lens is made from UV Fused Silica, a material known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. This material also offers a low coefficient of thermal expansion, making it resistant to thermal shock and dimensional changes.
The LB4330-A features an Anti-Reflection coating on both the front and back surfaces, specifically designed for the 350-700nm wavelength range. This coating enhances the lens's transmission capabilities, reducing unwanted reflections and improving overall system performance.
The lens's geometry is another notable feature. It has a center thickness of 4.4 mm and an edge thickness of 1.9 mm, providing excellent optical performance and durability. The lens's front and back radii of curvature are 68.3 mm and -68.3 mm, respectively, contributing to its high-quality imaging capabilities.
