棱镜把一束光拆成安静的色带

Minimal optical still life of a clear triangular glass prism beside a shallow round dish of water on matte white paper, one narrow sunbeam producing a restrained spectral band and subtle caustics, precise crisp edges, real glass refraction, airy editorial composition, no diagrams or lettering. Square 1:1 standalone finished image. No text, logo, watermark, border, grid, multi-panel layout or contact sheet.

透明三棱镜与一只浅圆水碟放在哑光白纸上，一束窄阳光形成克制光谱带与细微焦散。极简光学静物，边缘精确清楚，折射可信，编辑式留白，不加示意线或文字。 方形1:1独立完整成图。不要文字、标志、水印、边框、网格、多格排版或联系表。
