Semi Circular Glass Slab Manufacturer,Supplier and Exporter in India
Product Code : SCL-LAO-11184
The Lab Exports Semi Circular Glass Slab is manufactured from high-quality optical glass with a uniform refractive index. The block features perfectly flat, polished faces that ensure crisp, clean ray tracing without internal scattering or distortion. Its semi-circular shape is chosen to allow a ray of light entering through the curved surface to hit the flat surface at the center point without bending, simplifying geometric optics calculations.
This optical tool is vital for teaching students the fundamental behavior of light at boundaries. The durable composition resists superficial scratching under standard classroom handling, ensuring that light paths remain highly visible across multiple school terms. Designed for use alongside ray boxes, slit plates, and polar graph sheets, this slab fits seamlessly into standard laboratory experiment setups.
Key Features

Applications / Uses
Verifying Snell's Law ($n_1 \sin\theta_1 = n_2 \sin\theta_2$) by measuring angles of incidence and refraction.
Determining the critical angle of glass when shifting from a denser medium to a rarer medium.
Demonstrating the phenomenon of Total Internal Reflection (TIR) in physics laboratory classes.
Tracing light pathways inside comprehensive science kits focused on wave mechanics.
How to Use the Semi Circular Glass Slab
Place the semi circular glass slab flat onto a white sheet of paper or a polar coordinate graph sheet.
Trace the outline of the glass block accurately onto the paper using a sharp pencil.
Direct a narrow line of light from a laboratory ray box or laser pointer toward the center point of the flat face through the curved side.
Mark the entry, center, and exit paths of the light ray using small dots on the paper.
Remove the block, connect the dots using a ruler, construct a normal line, and measure the angles with a protractor.
Gradually increase the angle of incidence along the curved surface until the refracted ray travels along the flat edge to determine the critical angle.
Safety Note: Handle the glass block with care to avoid dropping it on hard surfaces, which may cause chipping or breakage. Always wear basic protective safety eyewear if using high-intensity laser pointers during the lab session.
Care & Maintenance
Clean the polished surfaces using a soft microfiber cloth and a mild glass cleaning solution to remove fingerprints and dust.
Store the glass block individually inside a padded container or its original wrapping to prevent glass-on-glass scratching.
Avoid exposing the optical glass block to extreme thermal shocks or high-heat environments.

Frequently Asked Questions
What is a semi circular glass slab used for?
A semi circular glass slab is primarily used in physics labs to study the refraction of light, measure critical angles, and observe total internal reflection without complicating geometric distortions from the entry boundary.
What material is this optical block made of?
This optical block is manufactured from high-purity, uniform optical glass that provides a stable, repeatable refractive index for standard student physics experiments.
Can it be used in schools?
Yes, this semi circular glass block is explicitly designed for middle schools, high schools, and introductory university physics laboratories due to its straightforward use case and structural durability.
Why is a semi-circular shape preferred for critical angle experiments?
The semi-circular shape is preferred because light rays directed at the center point through the curved boundary hit the glass perpendicular to the surface, meaning they enter without refracting, allowing accurate measurements solely at the flat exit boundary.
How do you clean fingerprints off the glass slab?
Fingerprints can be easily cleaned by wiping the slab with an optical microfiber cleaning cloth or using a small amount of standard isopropyl alcohol or mild lens cleaner.
