Glass Slab Manufacturer,Supplier and Exporter in India
Product Code : SCL-LAO-11185
The Lab Exports Rectangular Glass Slab is manufactured from highly homogeneous optical glass featuring a uniform refractive index. Every block is crafted with flat, highly polished viewing faces to ensure excellent optical clarity, reducing internal light scattering and aberration when tracking light paths. The side faces are ground smoothly to prevent handling injuries while maintaining structural alignment during pin-pointing or ray box procedures.
This essential optical instrument helps science educators effectively illustrate Snell's law and wave mechanics. Its premium glass composition offers superior durability against clouding, discoloration, and light surface scratches compared to acrylic or plastic alternatives. It integrates seamlessly into modern physics curriculum work alongside standard ray boxes, slit plates, and laser pointers.
Key Features
Premium Glass Formulation: High-grade optical glass provides reliable, repeatable refractive index parameters for student calculations.
Optically Polished Faces: Parallel polished surfaces allow clean laser or light ray passage with minimal distortion.
Safe Seamed Edges: Ground boundaries eliminate sharp corners, improving safety during student lab sessions.
High Scratch Resistance: Solid glass material withstands frequent wiping, cleaning, and general laboratory storage wear.
Standardized Geometry: Precision-cut rectangular dimensions simplify parallel alignment on student drawing sheets.

What's Included in the Kit
1 x Rectangular Glass Slab Block
1 x User instruction note for fundamental ray tracing experiments
Applications / Uses
Verifying the laws of refraction at parallel interfaces by mapping incident, refracted, and emergent rays.
Measuring the lateral displacement of a light ray passing through a parallel-sided medium.
Calculating the precise refractive index of glass using drawing pins and geometric construction.
Demonstrating the concept of apparent depth vs. real depth when viewing an object underneath the block.
Expanding optical configurations within modular science kits.
How to Use the Rectangular Glass Slab
Secure a clean sheet of white drawing paper onto a wooden softboard using board pins.
Place the rectangular glass slab flat at the center of the paper and trace its outer boundaries using a fine pencil.
Fix two tracing pins vertically on one side of the block to define an incident light ray path at an oblique angle.
Look horizontally through the opposite polished face of the slab and align two additional pins so they appear to form a straight line with the first two pins.
Remove the block and pins, then draw the incident, refracted, and emergent rays using a ruler.
Construct normals at the incidence points to calculate the angles of incidence ($i$) and refraction ($r$), verifying that the ratio $\sin i / \sin r$ equals the refractive index.
Safety Note: Protect the glass block from falling onto concrete floors, as impact can cause fracture or sharp edge chipping. Instruct students to hold the block gently by its ground edges to avoid smudging the polished viewing surfaces.
Care & Maintenance
Clean all fingerprints, grease, and dust using an optical microfiber cloth combined with standard lens cleaning solution or isopropyl alcohol.
Store the blocks separately inside their designated protective wrappers to stop glass-to-glass scraping during cart transport.
Keep the equipment in a dry cupboard away from corrosive fumes or high-humidity zones to avoid surface film development.

Frequently Asked Questions
What is a rectangular glass slab used for?
A rectangular glass slab is used in physics labs to demonstrate light refraction, measure the refractive index of glass, and visually analyze lateral displacement when light passes through parallel boundaries.
What material is this block made of?
This optical refraction block is made from uniform, high-purity optical glass, which offers a constant, standard refractive index unlike plastic blocks that vary or warp over time.
Is this glass block safe for school students?
Yes, it features ground safety edges that remove sharp corners, making it safe and easy to handle for students in middle schools, high schools, and colleges.
What is lateral displacement in a glass slab?
Lateral displacement is the perpendicular distance between the original path of the incident light ray and the path of the emergent light ray after passing through a medium with parallel faces.
How do you clean fingerprints from the optical surfaces?
Fingerprints can be cleaned by wiping the polished faces with a dry microfiber optical cloth or using standard lens cleaner to maintain maximum ray clarity.
