科技风实验室科研场景电子元件商业照片

A close-up, high-detail macro photograph of a custom green printed circuit board (PCB) resting on an electronics engineer's workbench. On the PCB, a tiny, bare square silicon photodetector chip is neatly mounted next to a miniature galvanometer scanner mirror assembly. In the softly blurred background, the glowing green lines of an oscilloscope screen and professional laboratory tools are visible. Warm, natural laboratory lighting, shallow depth of field, realistic textures of silicon, gold traces, and solder joints, clean composition, 3:2 aspect ratio, no text, no overlays
