Spectroscopy Lamps & Light Sources
Reliable Light for Reliable Measurements.
Spectroscopic and optical measurements depend on illumination that is stable, well defined and appropriate for the measurement method.
Laser 2000 provides light source technologies for spectroscopy, optical characterization, calibration and analytical measurements across UV, VIS and NIR.
What Are You Measuring?
Match the Source to the Measurement
Different measurement methods require different spectral characteristics and illumination conditions.
Absorption
Measure how strongly a sample absorbs light across the relevant spectral range.
Reflection
Characterize how light is reflected by surfaces, coatings and materials.
Transmission
Determine how light passes through materials and optical components.
Fluorescence & Emission
Provide appropriate excitation or measurement conditions for emitted optical signals.
Calibration
Create stable and known illumination conditions for reference and calibration measurements.
Find the Right Source
The source should be considered together with the complete measurement setup.
Key questions include:
Which spectral range needs to be covered? • Broadband or wavelength-specific illumination? • How much intensity is required? • How stable must the output be? • Is the source used for measurement or calibration? • How will it integrate with the spectrometer and detector?
Spectral range, stability and intensity are identified as key criteria, and the briefing specifically recommends selecting the source together with the detector and spectrometer.
