Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Bi-Concave Curvature. Outcome: Enables students to analyze the divergence of parallel light rays, supporting the mastery of the Lens Maker’s Formula and geometric optics.
Feature: Ground Edges and Polished Surfaces. Outcome: Ensures repeatable refractive data during Snell's Law verification, reducing experimental error in university-level practicals.
Feature: Variable Focal Length Availability. Outcome: Allows for the construction of complex optical benches (e.g., Galilean telescope models), facilitating the synthesis of multi-lens system theories.
International Logistics & Compliance
This Educational Instrument is prepared for global distribution via export-grade seaworthy crating (ISPM-15 compliant) to ensure optical integrity during transit. Procurement documentation includes the Manufacturer’s Authorization Form (MAF), Certificate of Origin, and comprehensive User Manuals in English. The tropicalized design is verified for long-term stability in high-humidity environments (up to 90% RH) and ambient temperatures reaching 45°C, ensuring durability in diverse geographical laboratory settings.
Why Source from the OEM?
As an established Manufacturing Export House, we provide vertical integration that eliminates the risks associated with third-party trading. Our in-house optical grinding and polishing facilities ensure that every batch is tested for uniformity in radius of curvature and refractive index. By sourcing directly, procurement officers gain access to direct factory spares, custom diameter configurations, and rigorous quality control protocols validated by our ISO 17025-compliant research associations.
