Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Precision Base-to-Base Geometry.Outcome: Allows students to synthesize the concept of virtual coherent sources facilitating the transition from theoretical wave optics to empirical observation.
Feature: Optically Worked Surfaces.Outcome: Minimizes scattering and parasitic light, enabling students to calculate fringe width with high reproducibility during laboratory examinations.
Feature: Acute Angle Calibrations.Outcome: Produces distinct interference fringes required for determining the wavelength of sodium vapor or laser light sources using the formula
Feature: Material Homogeneity.Outcome: Facilitates the measurement of the refractive index of thin films or glass slides through lateral fringe displacement analysis.
International Logistics & Compliance
Export-grade seaworthy crating (ISPM-15 compliant) is utilized for all international shipments to prevent mechanical shock and optical degradation during transit. Documentation provided includes the Manufacturer’s Authorization Form (MAF), optional IQ/OQ/PQ Certification for institutional audits, and comprehensive User Manuals in English. The instrument features a tropicalized design, tested for operational stability in environments up to 45°C and 90% humidity, ensuring the longevity of optical coatings and structural integrity in non-temperate climates.
Why Source from the OEM?
Procurement from this facility ensures complete vertical integration of the manufacturing lifecycle. Our facility utilizes in-house optical grinding and polishing to maintain sub-micron flatness and precise obtuse angle tolerances often compromised by secondary traders. Every unit is batch-tested for uniformity using monochromatic light verification to ensure fringe clarity and alignment. Direct sourcing guarantees factory-direct spares availability and technical support from the engineering team, bypassing intermediary logistics risks.
