Semicircular Refraction Cell Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11482

Scientifc Equipment Semicircular Refraction Cell is an educational optics laboratory apparatus designed for demonstrating refraction, critical angle, total internal reflection, refractive index, ray tracing, and light behaviour through liquid or transparent media. It is suitable for school science laboratories, college physics labs, STEM classrooms, optics practicals, and teacher-led demonstrations.

This refraction cell helps students observe how light bends when it passes from air into a liquid medium and from liquid back into air. Its semicircular design makes it useful for studying refraction at a flat surface while reducing unwanted bending at the curved surface when the light ray is directed through the centre.

Product Description

The Semicircular Refraction Cell by Scientifc Equipment is a practical ray optics teaching aid used to study refraction through liquids such as water or other suitable transparent fluids. The cell generally has a semicircular transparent body with a flat face and curved wall, allowing students to observe and trace the path of light rays clearly.

During experiments, the cell is filled with a suitable transparent liquid and placed on a ray optics board, Hartl optical disc, graph sheet, or optical bench setup. A narrow beam of light is directed through the cell to observe incident rays, refracted rays, emergent rays, critical angle, and total internal reflection under suitable conditions.

Scientifc Equipment Semicircular Refraction Cell is useful for teaching Snell’s law basics, refractive index comparison, optical density, critical angle, total internal reflection, and STEM-based optics learning.
