“A OPTICAL GLASS STUDY FORM No. 01 · CLEAR / REFRACTED”是使用 FontVibe AI 创作的玻璃文字效果。透明光学玻璃大写字母折射光线，边缘高光明亮并带焦散，倒映在深色台面上，背景是青绿色极光夜空。

Create a finished vertical 3:4 typography specimen poster. Render only these exact text strings, with spelling and punctuation intact: headline “A”; small subhead “OPTICAL GLASS STUDY”; footer “FORM No. 01 · CLEAR / REFRACTED”. Keep every line crisp and legible, with no additional lettering, symbols, watermark, or border. Center a monumental uppercase A, occupying roughly half the poster height. Build it as a sculptural display letter cast from pure, high-clarity, untinted optical crystal glass: broad geometric strokes, clean triangular counter, subtly liquid-pulled terminals, visible depth through the letter body, precise parallel facets at the cut edges, bright thin edge highlights, and restrained rainbow dispersion only at extreme angles. Strong internal refraction bends the lavender-blue background through the glass. Keep the letter fully transparent, never frosted or opaque. Set “OPTICAL GLASS STUDY” in small, widely tracked uppercase sans serif near the top, centered. Set “FORM No. 01 · CLEAR / REFRACTED” as a compact centered footer. The A is the sole focal point, with generous clear space around the typography. Place it on a low, transparent glass display plinth; its silhouette remains subordinate to the letter. A pale lavender-blue studio background carries diffused backlight and softly resolved caustic patterns beneath the A and plinth. Add sharp specular highlights on glass thickness transitions and soft light diffusion in the surrounding field, balancing precise glass edges with a gentle ambient glow. High-end optical product photography, ray-traced refraction, physically accurate caustics, subtle surface tension, clean studio rendering, strong contrast for readable copy.
