About This

• This Newton seven-color disk reproduces the classic experiment proving white light is composed of seven visible spectral colors. The disc is partitioned into seven independent fan-shaped sections coated with red, orange, yellow, green, cyan, indigo and violet pigments, perfectly restoring Newton’s optical spectrum research.
• The core experimental effect relies on human eye persistence of vision. When the color wheel rotates rapidly around the central spindle, the human retina cannot distinguish separate color sectors, and the seven spectral colors blend into uniform white vision to verify the white light synthesis rule.
• Equipped with an integrated stable chassis to fix the rotating spindle, the whole set maintains smooth high-speed rotation without shaking during long-term repeated optical observation. Compact dimensional design saves space on experimental workstations.
• Precise size matching: the supporting chassis measures 12cm × 8cm × 2.5cm, and the color mixing disc has a diameter of 5.5cm. The matched size ratio ensures obvious color mixing visual effects without oversized or tiny discs that weaken experimental observation.
• Specialized physical optics auxiliary experimental equipment for independent research on visible light composition and color superposition rules, realizing intuitive visualization of abstract light spectrum synthesis theories through simple rotary operation.
