Spectral & Light Measurement
Understand More Than Intensity.
Light can be characterised in many different ways.
Wavelength, spectral distribution, colour and intensity provide different information about an optical source or system—and each requires the appropriate measurement approach.
Laser 2000 provides spectral, colour and light measurement technologies for scientific and industrial applications.
Why Spectral Measurement Matters
Two light sources can produce similar intensity while having completely different spectral characteristics. Measuring wavelength and spectral distribution provides information that intensity measurements alone cannot reveal.
What Do You Need to Know?
Which Wavelengths Are Present?
Analyse wavelength and spectral distribution to understand the spectral characteristics of lasers, LEDs and other light sources.
Relevant technology: Spectrometers
What Colour Is Produced?
Quantify colour coordinates, chromaticity and colour consistency where visual appearance matters.
Relevant technology: Colorimeters
How Much Light Is Present?
Measure light levels where intensity is the primary parameter of interest.
Relevant technology: Light Meters
How Does Light Vary Spatially?
Characterise variations in light or colour across an illuminated area or source where spatial information is relevant.
Relevant technology: Imaging Colorimeters & 2D Light Measurement
These are the core selection and performance factors identified in the LED briefing.
Find the Right Measurement Approach
Start with the optical information you actually need.
Important selection parameters can include:
Wavelength Range • Spectral Resolution • Light Level • Source Type • Measurement Geometry • Spatial Resolution • Required Accuracy
A spectrometer, colorimeter and light meter answer different questions about the same source. In more demanding applications, several measurements may therefore be complementary.
Our experts can help determine which measurement technology—or combination of technologies—fits your application.

Frequently Asked Questions
Do I need a spectrometer, a colorimeter or a light meter?
A spectrometer measures wavelength and spectral distribution, a colorimeter quantifies colour and chromaticity, and a light meter measures overall light levels. Our experts help match the right instrument to your measurement question.
Can I measure how light varies across a surface?
Yes. Imaging colorimeters and 2D light measurement technologies can characterise spatial variations in light or colour across an illuminated area or source.
Do I need more than one type of measurement?
In more demanding applications, spectral, colour and light measurements can be complementary, since each answers a different question about the same source.
