Newton's Ring Model
Newton's Ring Model (Product Code: SCL-427/110) is a glass plate and convex lens assembly used to produce Newton's rings, circular interference fringes, for studying constructive and destructive interference in physics labs. This compact Newton rings apparatus holds both parts in a heavy aluminium frame 9 cm in diameter with a 5 cm aperture, and three spring-loaded screws adjust the contact pressure. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Newton's Ring Model Used For?
Where the convex lens rests on the flat glass plate, a thin wedge of air forms whose thickness grows outward from the point of contact. Light reflected from the top and bottom of this air film interferes, giving a dark central spot surrounded by concentric bright and dark rings, a direct picture of constructive and destructive interference.
Students can see the rings by eye in sunlight or under a fluorescent tube, where they appear coloured, and more sharply with a monochromatic source. Tighten the three spring-loaded screws evenly and only lightly, just enough to centre the rings, since excess pressure distorts the pattern. In college practicals the same principle is used with a travelling microscope to measure ring diameters.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer (OEM) of the Newton's Ring Model. The aluminium-framed assembly is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, universities, dealers and importers.

Frequently Asked Questions
What does the Newton's Ring Model show?
The Newton's Ring Model (SCL-427/110) shows circular interference fringes formed in the thin air film between a convex lens and a glass plate. The alternating bright and dark rings are used to study constructive and destructive interference of light.
What are the frame size and aperture of the Newton's Ring Model?
The Newton's Ring Model has a heavy aluminium frame 9 cm in diameter with a 5 cm aperture. The glass plate and convex lens are held inside the frame, and three adjusting screws control how firmly they press together.
What light source is needed for the Newton's Ring Model?
Interference fringes are clearly seen when the Newton's Ring Model is viewed in sunlight, fluorescent light or monochromatic light. White light gives coloured rings, while a monochromatic source gives sharper alternating bright and dark rings suited to measurement.
How are the three screws on the Newton's Ring Model adjusted?
The three spring-loaded screws on the Newton's Ring Model set the pressure between the two glass surfaces. Tighten them evenly and gently until the ring pattern is centred and steady; over-tightening distorts the rings and strains the glass.
Who manufactures the Newton's Ring Model?
The Newton's Ring Model is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Colleges, schools, dealers and importers buy directly from the manufacturer.
What should a Newton's Ring Model quote request include?
For a Newton's Ring Model quotation, state the quantity, whether it is for a school or college lab, any related optics items and the delivery location. Send it through the ScienceLab contact page; buyers in India and international markets are quoted by the manufacturer.
