Scientific Principles of Operation

1. Spectroradiometric Analysis

The LMS-6000F measures the absolute spectral power distribution (SPD) of light sources, decomposing emitted or reflected light into discrete wavelength components. This allows for the calculation of:

• Chromaticity coordinates (CIE 1931/1976)
• Korrelierte Farbtemperatur (CCT)
• Color Rendering Index (CRI, TM-30-20)
• Peak Wavelength and Dominant Wavelength

2. High-Speed Sampling for Dynamic Lighting

Unlike conventional spectrometers with slower integration times, the LMS-6000F utilizes real-time signal processing algorithms to capture transient lighting phenomena, such as PWM-driven LED flicker in automotive brake lights or pulsed medical illumination devices.

3. Multi-Angle Measurement Capability

For display and automotive lighting applications, the device supports gonio-spectrophotometric measurements, ensuring uniform color consistency across viewing angles—a critical parameter in OLED panel validation and aviation signal lighting.
