JGS1 Rod Lens is a cylindrical optical component made from UV-grade fused silica (JGS1), engineered for controlled one-dimensional light distribution. It is commonly used in laser line generation, structured illumination systems, machine vision, and optical scanning applications. The material provides excellent transmission from UV to near-infrared wavelengths with low absorption and high laser damage threshold. The cylindrical geometry enables precise beam shaping along one axis while maintaining optical stability. These lenses are produced with high-precision polishing to ensure consistent curvature and surface quality.
