Technical Specifications of the LISUN LMS-6000 Luminance Meter

The LMS-6000 is a high-performance luminance meter with the following key specifications:

The LMS-6000’s wide dynamic range and high accuracy make it suitable for both low-light applications (such as aviation panel lighting) and high-intensity measurements (such as automotive headlamps or LED displays).

Measurement Principles and Optical Design

The LMS-6000 operates on the principle of photoelectric detection, where incoming light is filtered to match the CIE standard photopic curve (V(λ)), ensuring human-eye-correlated luminance readings. The optical system consists of:

1. Objective Lens System – Focuses light onto the detector while controlling the field of view (FOV).
2. Spectral Correction Filter – Adjusts the sensor response to align with the CIE V(λ) function.
3. High-Sensitivity Photodiode – Converts light intensity into an electrical signal with minimal noise.
4. Digital Signal Processing (DSP) – Enhances measurement stability and compensates for environmental variations.

This design ensures compliance with ISO/CIE standards, making the LMS-6000 a trusted tool for scientific and industrial applications.
