Semi Circular Glass Slab | Optical Glass Block for Physics Laboratories

The Semi Circular Glass Slab by ELMO Agencies is a precision optical apparatus designed for demonstrating the fundamental principles of light and optics in physics laboratories. Manufactured from high-quality transparent optical glass, this laboratory instrument is widely used for experiments involving refraction, critical angle, total internal reflection, and refractive index measurement.

With a 90mm (3.5-inch) diameter and 15mm thickness, the slab offers excellent optical clarity and accurate geometry for reliable experimental results. As a company specializing in scientific laboratory equipment manufacturing in Ambala, ELMO Agencies produces durable educational instruments trusted by schools, colleges, engineering institutes, and research laboratories across India.

What Is a Semi Circular Glass Slab?

A Semi Circular Glass Slab is an optical glass block shaped like a semicircle, specifically designed for studying the behaviour of light. Its unique shape allows light rays to enter through the curved surface almost normally, reducing unwanted refraction at the point of entry. This enables students to observe the refraction occurring at the flat surface more accurately, making experiments easier to perform and understand.

The slab is an essential teaching aid for optics practicals and helps students verify important concepts such as Snell’s Law, critical angle, and total internal reflection through hands-on experimentation.

Working Principle

The Semi Circular Glass Slab works on the principle of refraction of light.

When a ray of light enters through the curved surface, it passes almost undeviated because it strikes the surface nearly perpendicular to it. As the light reaches the flat surface, it bends according to the refractive index of glass. By changing the angle of incidence, students can observe:

• Refraction of light

• Critical angle

• Total Internal Reflection (TIR)

• Refractive index determination using Snell’s Law

This design makes the apparatus highly effective for visual learning and accurate laboratory observations.
