Stabilized Frequency Raman Laser
The Stabilized Frequency Raman Laser system eliminates coma and astigmatism through optimized optical design balancing high resolution with high sensitivity detection. The unit operates across 130 to 2800 cm⁻¹ spectral range with 7 cm⁻¹ resolution and ±1.5 cm⁻¹ wavenumber accuracy. Dual excitation wavelength options at 532nm and 785nm accommodate fluorescence-prone samples and non-fluorescent materials. A 2048-pixel linear array CCD detector maintains thermoelectric cooling at 14°C for low-noise performance. Integration time adjusts from 0.10 milliseconds to 60 seconds for optimal signal collection.
Precise temperature control ensures stable spectral output during extended measurement sessions. The system measures 180 mm × 130 mm × 280 mm at under 3 kg, providing field portability with comprehensive accessories for outdoor gemstone analysis. Intelligent software features automatic peak finding and fluorescence background subtraction without manual baseline correction. The integrated database contains over 200 gemstone types for automated identification through spectral matching algorithms. Expandable software architecture supports custom database creation for proprietary reference libraries.
Gemological laboratories deploy the Stabilized Frequency Raman Laser for non-destructive gemstone authentication and treatment detection. Jewelry retailers verify stone identity and synthetic versus natural origin at point-of-sale locations. Customs inspectors examine high-value gem shipments for import classification and duty assessment. Museums authenticate historical jewelry collections and detect conservation treatments applied to specimens. Mining operations conduct rapid mineral identification during exploration and quality grading procedures.
Tactical Supply Pakistan supplies this gemological analysis system to organizations requiring portable Raman identification capabilities with temperature-stabilized performance for consistent results across field and laboratory environments.
Why does the system offer two different excitation wavelengths?
The 532nm wavelength provides strong Raman scattering for most gemstones while 785nm reduces fluorescence interference in samples like rubies and emeralds that overwhelm detection at shorter wavelengths.
