LB4265-C UV Fused Silica Bi-Convex Lens; Dia:1 in; f=150.0 mm ARC 1050-1700nm

The LB4265-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 wavelength of 588nm, making it ideal for applications that require precise focusing and manipulation of UV light.

The lens is constructed from UV fused silica, a material known for its exceptional transparency in the UV range. This material also offers high thermal stability and resistance to chemical etching, making it a robust choice for various optical applications. The lens has a diameter of 1 inch (25.4mm) and a focal length of 150.0mm, providing a large working distance and a wide field of view.

The LB4265-C features a unique anti-reflection coating, denoted as "tho c bbar", on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission in the 1050-1700nm range, further enhancing the lens's performance in UV applications.

The lens's geometry is also noteworthy, with both surfaces featuring a radius of curvature of 137.5mm. This bi-convex design provides a large numerical aperture, enabling the lens to collect and focus light efficiently. The lens has a center thickness of 3.2mm and an edge thickness of 2mm, providing structural rigidity while minimizing unwanted optical aberrations.
