LB4743-C UV Fused Silica Bi-Convex Lens; Dia:5 mm; f=10.0 mm ARC 1050-1700nm

The LB4743-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens, with a diameter of 5 mm, is specifically engineered for use within the wavelength range of 1050-1700nm, making it suitable for a wide range of applications in the infrared spectrum.

The lens features a focal length of 10.0 mm, indicated by the 'f' parameter, which is a critical specification for determining the lens's magnification and field of view. The 'efl' or effective focal length, is 9.2 mm, a slight deviation from the focal length due to the lens's curvature.

The lens is made from UV Fused Silica, a high-performance material known for its excellent transmission properties across a broad spectrum, including the UV and visible ranges. This material also offers high thermal stability and resistance to chemical environments, making it a robust choice for various applications.

The LB4743-C is coated with a broadband anti-reflection coating (ARC), specifically designed for the 1050-1700nm range. This coating reduces surface reflections, thereby increasing the lens's transmission efficiency and improving overall system performance.

The lens's geometry is spherical, with radii of curvature 'r1' and 'r2' at 8.8 mm and -8.8 mm respectively. The edge thickness is 1.5 mm, while the center thickness is 2.2 mm, providing a robust structure while maintaining a compact form factor.
