PMMA Rod
Poly(methyl methacrylate) (PMMA) rods are valued for their optical clarity, mechanical strength, and adaptability, making them essential in scientific and industrial applications. They are widely used in optical systems such as waveguides, lenses, and light transmission devices, with ongoing exploration into advanced technologies like all-optical modulation. Configurations combining PMMA rods with materials like black phosphorus have shown potential for responsive optical devices, including modulators and switches. Additionally, their lightweight and moldable properties make them ideal for innovative applications in automotive, aerospace, and biomedical engineering, driving advancements in materials research and development.
