Optical Device for Color Demonstration Color Disk
Optical Device for Color Demonstration Color Disk (Product Code: SCL-337/035) is a colour-disc demonstration apparatus used to show that white light is made up of spectral colours in school physics classes. A 200 mm disc printed with two sets of spectrum colours spins on a hand-turned rotor, while six LED bulbs, run from a mixer control box, add a light-mixing display on the 32 cm tall unit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Color Disk Device Used For?
The device recreates Newton’s colour-disc experiment. At rest, students see the separate bands of the spectrum; when the handle spins the disc quickly, the eye can no longer separate the colours and the disc appears nearly white. The lesson is that white light is a mixture of colours — the reverse of splitting light with a prism.
The six LED bulbs, operated from the mixer control box, let the teacher show how coloured lights combine, a natural follow-on in any optics experiment for school classes on light and colour. Turn the handle steadily rather than in jerks for an even blend, dim the room lights for the LED part, and keep the disc face clean so the colours stay bright.
OEM Manufacturer
The Color Disk device comes from Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, which is the OEM (original equipment manufacturer) and assembles it at its own licensed factory at Saha, Ambala, Haryana, India. Schools and colleges, as well as dealers and importers, are supplied factory-direct, and questions about a replacement disc or power adapter go to the maker — ask us.

Frequently Asked Questions
What does the Optical Device for Color Demonstration Color Disk demonstrate?
The Optical Device for Color Demonstration Color Disk demonstrates that white light is a mixture of colours. When its 200 mm spectrum disc spins fast, the colours blend and the disc looks nearly white; the LED bulbs add a coloured-light mixing display.
What parts come with the Color Disk device?
The Optical Device for Color Demonstration Color Disk comes with a mixer control box, a power adapter, six LED bulbs, a circular frame, a coloured disc with two sets of spectra, a rotor with a rotating handle and a plastic base with rubber pins.
How big is the Optical Device for Color Demonstration Color Disk?
The Optical Device for Color Demonstration Color Disk stands 32 cm tall on a plastic base of 120 x 120 mm with rubber pins, and its colour disc is 200 mm in diameter, compact enough for a front-bench demonstration.
Why does the spinning disc look greyish rather than pure white?
On the Optical Device for Color Demonstration Color Disk, printed colours reflect only part of the light falling on them, so the blended disc often looks off-white or grey. Good lighting and a steady, fast spin give the clearest result.
Who manufactures the Optical Device for Color Demonstration Color Disk?
The Optical Device for Color Demonstration Color Disk is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India, and supplied direct to institutions, dealers and importers.
Can the Color Disk device be ordered for several schools?
Yes. ScienceLab supplies the Optical Device for Color Demonstration Color Disk in single units or larger quantities for school projects and dealers in India and international markets. Share the quantity and destination via the contact page.
