LB4140-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=150.0 mm ARC 350-700nm

The LB4140-A is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties and resistance to thermal shock. This lens, with a diameter of 2 inches and a focal length of 150.0 mm, is designed for use in the ARC 350-700nm range, making it suitable for applications that require precise focusing and manipulation of light in the visible spectrum.

The lens geometry is spherical, with a center thickness of 7.8 mm and an edge thickness of 3 mm. The radii of curvature for the first and second surfaces are 136.8 mm and -136.8 mm, respectively, resulting in a back focal length of 147.3 mm. The lens has a high degree of symmetry, which helps to minimize optical aberrations.

The LB4140-A is coated with Thorlabs' anti-reflection coating, which is designed to reduce surface reflections and increase transmission. The coating is applied to both the front and back surfaces of the lens, further enhancing its performance in the specified wavelength range.
