Thin-Film Laser Resistor Trimmer
Thin-film laser resistor trimmer. A micrometer-scale laser spot scans the resistor surface, melting and vaporizing the resistive paste layer to form a groove of specified depth and change conductive cross-section or length. A precision measurement system measures resistance in real time and stops emission at the target, bringing an initially lower resistance into the required tolerance. A key system for chip thin-film resistor production, it trims ceramic-substrate chip thin-film resistors and thin-film hybrid circuits. Resistance range:0.1Ω-500MΩ. Trimming accuracy:±0.05/±0.1/±0.5/±1(%).

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.
