Glass Prism
Product Code : SCL-PLE-11782
The JLab India Glass Prism is a precision-manufactured optical component engineered for the empirical study of light refraction, dispersion, and the geometry of deviation. Optimized for Secondary and University-level physics, this equilateral triangular prism is designed to resolve white light into its constituent spectral components. It facilitates the quantification of refractive indices and the verification of the relationship between incident and emergent rays within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Refractive Interface: Facilitates student visualization of how light bends at the interface of two media, supporting Geometrical Optics Module 101.
- Refractive Index Quantification: Enables the physical study of optics, allowing learners to apply the prism formula n=sin(2A)sin(2A+Dm) where A is the prism angle and Dm is the angle of minimum deviation.
- Spectral Analysis: Supports the analysis of "chromatic dispersion," demonstrating how different wavelengths of light (colors) travel at different speeds through the glass medium.
- Deviation Evaluation: Allows students to evaluate the relationship between the angle of incidence and the angle of deviation, fostering a deeper understanding of wave behavior.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring individual velvet-lined protective cases and shock-resistant foam to prevent chipping or internal fractures during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a datasheet specifying the refractive index for the Sodium D-line.
- Durability: Tropicalized design featuring anti-fungal coatings to prevent "clouding" or surface degradation in high-humidity laboratory climates.
Direct OEM Sourcing Advantages
Procuring the JLab India Glass Prism directly ensures vertical manufacturing control:
- In-House Surface Polishing: Every prism face is batch-checked for flatness and parallelism to ensure clean, sharp spectral resolution without "ghosting."
- Precision Angle Milling: Every unit is verified to be exactly 60? (within ±0.1?), which is critical for accurate calculations of minimum deviation.
- Direct Factory Spares Availability: Guaranteed availability of matching prism tables, light sources (ray boxes), and specialized slit assemblies to maximize laboratory ROI.
- Manufacturing Control: Direct oversight of the glass-melting process ensures zero bubbles or striae, providing students with a clear, high-contrast spectrum.
