The LB4280-B is a high-quality UV Fused Silica Bi-Convex Lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens boasts a diameter of 6 mm and a focal length of 10.0 mm, making it a versatile choice for a wide range of optical applications.
The lens is constructed from UV Fused Silica, a material known for its exceptional transparency across a broad spectrum, from 190 to 2000 nm. This makes the LB4280-B particularly suitable for use in ultraviolet (UV) applications. The lens's geometry is characterized by its edge thickness of 1.5 mm and center thickness of 2.6 mm, contributing to its robustness and optical performance.
The LB4280-B features an Anti-Reflection Coating (ARC) optimized for the 650-1050 nm wavelength range. This coating reduces surface reflections, thereby enhancing transmission and improving overall system performance. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
The lens's shape is spherical, with radii of curvature of 8.8 mm for the first surface and -8.8 mm for the second. This bi-convex design provides a large numerical aperture, making it ideal for imaging and beam shaping applications.
