The rod lens is a cylindrical optical component that combines the optical performance of a lens and a mechanical light guiding structure. It is mainly used in scenarios such as laser shaping, fiber coupling, and endoscopic lighting. Its design with a specific length-to-diameter ratio (L/D) can achieve unique optical effects.
Multifunctional optical performance: beam homogenization, optical path folding.
Compact mechanical design: High integration, integrated structure, resistant to environmental impact.
Material diversity: Optical glass and infrared crystals can all be customized.
