LB4293-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=1000.0 mm ARC 350-700nm
The LB4293-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 2 inches, or 50.8 millimeters, and a focal length of 1000.0 millimeters, making it a versatile choice for a wide range of optical applications.
The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a broad spectrum, from 350 to 700 nanometers. This makes the LB4293-A particularly suitable for applications that require high transmission in the ultraviolet and visible regions of the spectrum.
The lens features a spherical shape, with radii of curvature of 919.6 millimeters for both the front and back surfaces. This design results in an effective focal length of 1000.0 millimeters and a back focal length of 998.7 millimeters. The lens has a central thickness of 3.7 millimeters and an edge thickness of 3 millimeters, providing robustness and durability.
The LB4293-A is coated with Thorlabs' Anti-Reflection Coating (ARC), which is designed to minimize surface reflections and increase transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
