Newton’s Color Disc
Model Number: MTO-35
Newton’s Color Disc is a classic optics apparatus used to demonstrate the relationship between the visible spectrum and white light. Micro Technologies supplies the apparatus with a circular disc divided into seven spectrum colors and mounted vertically on a stable metal stand. A hand-operated gear mechanism rotates the disc rapidly, causing the individual colored sectors to visually blend so that the rotating surface appears approximately white or pale grey. This provides a simple and effective demonstration of additive color perception and the composition of white light. The manually operated arrangement requires no electrical power, while its sturdy construction supports repeated laboratory use. It is suitable for physics laboratories, optics demonstrations, universities, colleges, training laboratories, and institutional procurement.
Product Specification
The Newton’s Color Disc is a manually operated optical apparatus used to demonstrate how the colors of the visible spectrum can visually combine when presented in rapid succession. The apparatus provides a straightforward way to investigate color perception and the relationship between spectral colors and white light.
The main component is a circular disc divided into seven colored sectors representing the principal colors traditionally associated with the visible spectrum. The disc is mounted vertically on a rigid metal stand and connected to a hand-driven gear mechanism. Turning the handle transfers rotational motion through the gears, allowing the disc to reach a sufficiently high speed for the individual color sectors to become difficult for the eye to distinguish separately.
Micro Technologies supplies Newton’s Color Disc as a complete mechanical demonstration apparatus. As rotational speed increases, persistence of vision and temporal color integration cause the separate colored regions to visually blend. Instead of seeing distinct sectors, the observer sees a much lighter combined appearance, typically perceived as whitish or pale grey depending on the illumination, pigments, rotational speed, and viewing conditions.
The gear-driven mechanism provides convenient manual operation without requiring a motor, battery, or external electrical supply. This keeps the apparatus simple to operate and reduces maintenance requirements.
Its stable metal stand supports the rotating assembly during operation, while the vertically mounted disc remains clearly visible to observers. The arrangement is suitable for demonstrating color mixing, visible-spectrum concepts, and fundamental principles associated with light and human visual perception.
With its simple mechanical operation, clearly divided spectrum disc, and reusable construction, Newton’s Color Disc provides an economical and practical addition to physics and optics laboratory equipment collections.

FAQs
What is Newton’s Color Disc used for?
Newton’s Color Disc is used to demonstrate how different spectrum colors visually blend when the disc rotates rapidly. It helps investigate fundamental concepts related to light, color, and visual perception.
How does Newton’s Color Disc work?
The disc contains seven colored sectors. When rotated rapidly, the eye can no longer clearly resolve each sector independently, and the colors visually blend into a lighter, approximately whitish appearance.
How many colors are present on the disc?
The standard Newton Color Disc contains seven colored sections representing the traditional visible spectrum color sequence.
Why does the rotating disc appear whitish?
Rapid rotation causes the colors to be integrated by the visual system over time. Their combined visual effect produces a pale or approximately white appearance under suitable viewing conditions.
Is the apparatus electrically operated?
No. The standard apparatus is manually operated. A hand-driven gear mechanism rotates the color disc, so no electrical power supply is required.
What is the purpose of the gear mechanism?
The gear mechanism transfers and increases rotational movement from the hand-operated drive to the disc, allowing it to rotate fast enough for effective visual color blending.
Does Newton’s Color Disc require calibration?
No routine calibration is required. The disc should rotate freely, and the gear mechanism should remain correctly aligned for smooth operation.
How durable is the apparatus?
The metal supporting structure provides good durability for regular laboratory handling. Proper operation and storage help maintain smooth mechanical performance over a long service period.
How should Newton’s Color Disc be maintained?
Keep the disc clean and dry and periodically inspect the rotating mechanism. Avoid bending the disc or applying excessive force to the gears and handle during operation.
Can Newton’s Color Discs be ordered in bulk?
Yes. Bulk quantities can be supplied for physics laboratories, optics laboratories, universities, colleges, training facilities, distributors, and institutional laboratory projects.
Can the apparatus be customized?
Disc dimensions, supporting arrangements, packaging, and certain mechanical configurations may be customized for bulk requirements depending on manufacturing feasibility.
How is the apparatus packed for shipping?
The disc, stand, handle, and gear mechanism are protected against bending, impact, and unwanted movement during transportation. Bulk and export packaging can also be arranged.
