Semi-Circular Lens Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11455

Scientifc Equipment Semi-Circular Lens is an educational optics laboratory component designed to demonstrate refraction, critical angle, total internal reflection, ray tracing, refractive index, and light behaviour through a curved transparent medium. It is suitable for school science laboratories, college physics labs, STEM classrooms, optics practicals, and teacher-led demonstrations.

The semi-circular lens helps students observe how light bends when it enters or leaves a transparent material. Its flat face and curved surface make it especially useful for studying refraction at different angles, normal incidence through the curved face, and total internal reflection when light travels from a denser medium to a rarer medium.

Product Description

The Semi-Circular Lens by Scientifc Equipment is a practical optics teaching aid used in physics laboratories for refraction and light ray experiments. It is generally made from optical glass, acrylic, or other suitable transparent optical material as per supplied model configuration.

In a typical experiment, the semi-circular lens is placed on a graph sheet or optical board. A narrow beam of light is directed through the lens using a ray box or light source. Students can trace the incident ray, refracted ray, reflected ray, and emergent ray to understand how light changes direction at transparent surfaces.

Scientifc Equipment Semi-Circular Lens is useful for teaching Snell’s law, refractive index, critical angle, total internal reflection, light deviation, ray diagrams, and practical optical applications such as optical fibres, prisms, lenses, and scientific instruments.
