Описание: A half-wave plate (λ/2 wave plate) is an optical component based on birefringent materials. It achieves a 180° phase retardation for specific wavelengths (such as 1550 nm and 1064 nm), allowing precise control of the direction of linearly polarized light or the state of elliptically polarized light. Its key features include a phase retardation accuracy of ±2° (@632.8 nm), wideband adaptability (from UV 190 nm to terahertz 10 THz), and a high laser damage threshold. Material options include quartz and magnesium fluoride (UV-optimized), meeting diverse application needs. Typical applications include polarization multiplexing in optical communications, high-power laser processing, quantum computing, and consumer electronics. As a core component of optoelectronic systems, the half-wave plate continues to drive the advancement of industrial manufacturing, scientific instruments, and cutting-edge technologies toward higher speed, miniaturization, and extreme environmental adaptability.#optical #optics
