Glass Slab
Product Code : SCL-PLE-11730
The JLab India Glass Slab is a precision-engineered optical medium designed for the empirical study of light refraction and lateral displacement. Optimized for Secondary and University-level physics, this rectangular slab features high-clarity optical glass with precision-ground faces. It facilitates the quantification of the refractive index and the verification of Snell’s Law within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Refraction Interface: Facilitates student visualization of the bending of light as it transitions between media of different optical densities, supporting Geometrical Optics Module 101.
- Refractive Index Quantification: Enables the physical study of light speed reduction, allowing learners to apply the formula n=sin(i)/sin(r) using the pin-and-tracing method.
- Lateral Shift Analysis: Supports the analysis of why an emergent ray remains parallel to the incident ray but is laterally displaced by a distance d.
- Apparent Depth Evaluation: Allows students to evaluate the optical illusion of "shallowing" when an object is viewed through the slab, demonstrating the relationship n=Real Depth/Apparent Depth.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring individual anti-scratch wrapping and high-density foam partitioning to prevent mechanical stress or "scuffing" during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and batch-specific refractive index data.
- Durability: Tropicalized design featuring chemical-stable glass that resists "clouding" and surface oxidation in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the JLab India Glass Slab directly ensures vertical manufacturing control:
- In-House Precision Polishing: Every slab is batch-tested for parallelism using laser interferometry to ensure the emergent ray is perfectly parallel to the incident ray.
- Batch-Tested for Uniform Reliability: Samples from each melt are verified for internal homogeneity to ensure there are no striae or bubbles that could distort ray paths.
- Direct Factory Spares Availability: Guaranteed availability of matching prisms, semi-circular slabs, and specialized ray-box light sources to maintain complete laboratory optical kits.
- Manufacturing Control: Direct oversight of the annealing process ensures the glass is free from internal strain, providing a clear and consistent medium for both white-light and laser-based demonstrations.
