Newton’s Colour Disc Model Manufacturer,Supplier and Exporter in India
Product Code : SCL-LAO-11215
The Newton’s Colour Disc Model manufactured by Lab Exports is a highly durable educational physics model engineered to clarify optics concepts. The unit consists of a high-impact, balanced 150mm circular disc divided into seven multi-colored sectors matching the primary colors of the visible light spectrum (red, orange, yellow, green, blue, indigo, and violet). This disc is mounted securely to a low-friction spindle drive system.
To ensure steady classroom demonstration, the mechanical system is mounted on a heavy, robust metal support pillar anchored to a non-slip cast iron base. The manual driving mechanism utilizes a high-ratio pulley wheel with a secure driving belt and integrated crank handle. This design allows operators to reach the necessary rotational velocity effortlessly to demonstrate additive color synthesis. It is a vital tool for schools updating their physics lab equipment inventory and practical school education kits.
Key Features
Vibrant Spectral Sectors: Features accurately colored, non-fading segments representing red, orange, yellow, green, blue, indigo, and violet.
Balanced 150mm Disc: Precision-balanced disc design minimizes axial wobble or vibration during high-speed spinning.
High-Ratio Pulley Drive: Hand-driven mechanical pulley system delivers rapid rotation speeds with minimal physical effort.
Heavy Cast Iron Base: Solid, low-center-of-gravity base ensures steady desktop placement during classroom experiments.
Durable Construction: Built using heavy-gauge steel pillars and wear-resistant polymer components for long-term classroom utility.
Purely Mechanical Design: Requires no electrical power or external batteries, allowing for reliable use in any educational setting.

How to Use the Newton’s Colour Disc Model
Place the apparatus on a flat, level, and secure laboratory work surface.
Ensure that the rubber drive belt is seated correctly around both the small spindle pulley of the disc and the large hand-pulley wheel.
Position students around the model so they have an unobstructed, direct line of sight to the face of the colored disc.
Turn the crank handle of the larger wheel slowly to confirm the belt is aligned and the disc rotates smoothly without catching.
Rotate the crank handle rapidly in a clockwise direction to accelerate the disc's rotational velocity.
Observe how the distinct individual colored sectors visually blend together into a uniform white or light grey shade as velocity increases.
Safety Note: Keep fingers, loose clothing, and long hair away from the rotating wheels and rubber drive belt during operation. Do not touch the spinning disc to stop its motion; allow it to decelerate naturally.
Care & Maintenance
Clean the colored surface of the disc using a dry, soft, non-abrasive microfiber cloth to prevent scratches.
Do not expose the disc to direct water, strong chemical solvents, or prolonged sunlight to protect the color sectors from fading.
Apply a tiny drop of lightweight machine oil to the primary rotation shafts occasionally to maintain silent, low-friction operation.
Store the model in a cool, dry, and dust-free storage cabinet along with other critical educational laboratory instruments.

Frequently Asked Questions
What is a Newton's Colour Disc used for?
It is used in physics classes to demonstrate additive color mixing, proving that white light is composed of the combined colors of the visible spectrum.
Why does the disc look white when it spins rapidly?
Due to the persistence of vision, the human eye retains individual color impressions for a fraction of a second. When the disc spins rapidly, these impressions overlap, causing the brain to perceive the additive mixture as white or light grey.
What material is the colored disc made of?
The disc is made of high-quality, durable polymer [confirm] with vivid, UV-resistant color sectors to prevent fading under bright classroom lights.
Can the drive belt be replaced if it breaks?
Yes, the rubber drive belt is easily replaceable with standard industrial O-rings or replacement bands provided directly by Lab Exports.
Does this model require an external electricity supply?
No, this model is purely mechanical and hand-driven, making it ideal for classrooms without immediate access to electrical outlets.
