Semicylinder Manufacturer,Supplier and Exporter in India

Product Code : SCL-OS-12894

The Educational Instrument Semicylinder is used in ray optics lessons where students need to observe how light bends when it passes from air into a transparent medium. Its semicircular shape helps reduce unwanted refraction at the curved surface when the ray is directed toward the centre.

This product is suitable for use with a ray box, laser ray box, LED light source, optical bench, protractor sheet, white screen, and optical track. Since a standalone Educational Instrument SKU was not verified, exact material, dimensions, optical grade, and packing should be confirmed before tender submission.

Key Features

Semicircular optical block for practical refraction and ray-tracing experiments.

Useful for Snell’s law, refractive index, critical angle, and total internal reflection demonstrations.

Curved surface supports cleaner entry-ray alignment toward the centre of curvature.

Compatible with ray boxes, laser ray boxes, optical benches, protractor sheets, and screens.

Supports hands-on comparison of incident, refracted, and internally reflected rays.

Suitable for supervised school, college, university, TVET, and STEM physics laboratories.

Can be used as part of a complete geometrical optics teaching setup.

Technical Specifications

Applications / Uses

Verifying Snell’s law using measured incidence and refraction angles.

Determining the refractive index of the transparent block material.

Demonstrating critical angle and total internal reflection.

Tracing light paths through curved and flat optical surfaces.

Using with Geometric Optics apparatus for structured refraction experiments.

Pairing with the Light and Optics Demo Kit STEM Lab for classroom beam demonstrations.

How to Use the Semicylinder

Place a white sheet, protractor layout, or optical bench on a stable laboratory table.

Position the Semicylinder so its flat face aligns with the protractor reference line.

Direct a narrow ray from a ray box, laser ray box, or LED light source toward the curved face.

Align the ray toward the centre of curvature for cleaner refraction observation.

Mark the incident ray, normal line, refracted ray, and emergent ray.

Change the angle of incidence and record the new refraction angle.

Use the measured values to verify Snell’s law or estimate refractive index.

Safety note: never look directly into laser beams, bright lamps, or concentrated reflected light. Use only under teacher or laboratory supervision.

Care & Maintenance

Handle the Semicylinder by the edges to avoid fingerprints on optical surfaces.

Clean with a soft microfiber cloth or approved optics cleaning material.

Store in a dry, dust-free box to prevent scratches and surface damage.

Keep away from heat, solvents, abrasive paper, chemicals, and rough handling.

Frequently Asked Questions

What is a Semicylinder used for in optics?

A Semicylinder is used to demonstrate refraction, Snell’s law, refractive index, critical angle, and total internal reflection in physics optics experiments.

Why is a semicircular block used for refraction experiments?

A semicircular block lets the light ray enter through the curved surface toward the centre, reducing unwanted bending at the entry surface and making the refraction at the flat face easier to study.

Can this Semicylinder be used with a ray box?

Yes. It can be used with a ray box, laser ray box, LED light source, optical bench, screen, and protractor layout under supervision.

Is the Semicylinder suitable for school laboratories?

Yes. It is suitable for supervised school, college, university, TVET, and STEM physics laboratories.

What material is the Semicylinder made from?

The verified Educational Instrument content references semicircular glass and acrylic optical blocks in related optics kits. Confirm the supplied standalone material before publishing final specifications.

Does it include a protractor sheet or holder?

The standalone supplied accessories are not verified. Confirm whether a protractor sheet, holder, or storage case is included before final procurement documentation.
