Spectrometer
Product Code : SCL-PLE-11701
The JLab India Spectrometer is a high-precision optical instrument engineered for the empirical study of light properties, including refractive indices, dispersive power, and wavelength measurement. Optimized for University-level physics and advanced optics, this apparatus facilitates the quantification of the angle of minimum deviation (Dm) with arc-minute accuracy. It provides a stable, multi-axis platform for verifying the wave nature of light and the specific emission spectra of various elements within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Slit-Collimator Interface: Facilitates student visualization of parallel light-ray generation, supporting Optics Module 301.
- Angular Quantification: Enables the physical study of beam deviation, allowing learners to apply Vernier scale readings to determine the apex angle (A) of a prism.
- Refractive Index Analysis: Supports the analysis of the relationship between wavelength and refraction through the determination of minimum deviation.
- Spectral Resolution Evaluation: Allows students to evaluate the difference between continuous spectra (incandescent) and line spectra (gas discharge) when used with a diffraction grating.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring specialized internal shock-stabilization to protect the precision-aligned optical axes.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and illustrated Technical User Manuals in English.
- Durability: Tropicalized design featuring anti-fungal lens coatings and corrosion-resistant metallic scales to ensure long-term laboratory ROI in varied climates.
Direct OEM Sourcing Advantages
Procuring the JLab India Spectrometer directly ensures vertical manufacturing control:
- In-House Precision Graduation: Circular scales and Verniers are batch-tested for concentricity and etching accuracy to ensure zero-lag readings.
- Batch-Tested for Optical Alignment: Every telescope and collimator undergoes a focal-coincidence check to ensure sharp, aberration-free images of the slit.
- Direct Factory Spares Availability: Guaranteed availability of replacement Ramsden eyepieces, diffraction grating holders, and leveling screws.
- Manufacturing Control: Direct oversight of the bearing assembly ensures ultra-smooth rotational movement of the telescope and table, critical for detecting fine spectral lines.
