Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
Within cutting‑edge ultrafast photonics research, asynchronous optical sampling (ASOPS) and synchronous sampling serve as fundamental technologies for terahertz excitation detection, coherent Raman imaging and other time‑resolved spectroscopy experiments.
Shanghai Connet Laser Technology Co., Ltd. focuses on technological innovation, delivering cutting-edge photonic products & solutions for industrial lasers, LiDAR, fiber optic sensing, coherent telecom, cold atom physics and precision spectroscopy research & mass manufacturing.
