Standard Light Source Calibration System

The SLS-50W/SLS-100W Standard Light Source is engineered for precision calibration of LISUN LPCE-2 High-Precision Spectroradiometer Integrating Sphere Systems and LPCE-3 CCD Spectroradiometer Integrating Sphere Compact Systems. The calibration certificate accompanying this standard light source is fully traceable to NIM (National Institute of Metrology, China) and NIST (National Institute of Standards and Technology, USA), ensuring compliance with international metrological standards including IEC 60969.

Proper calibration of integrating spheres requires matching standard lamp power to sphere dimensions. The following table specifies the appropriate standard light source models for various integrating sphere sizes:

The SLS-150W Standard Intensity Light Source is specifically designed for calibration of LSG Series Goniophotometers and Goniospectroradiometers. This calibration system also provides NIM/NIST-traceable certification to meet quality assurance requirements in photometric testing laboratories.

The SLS-UV UV Standard Light Source with Integrated Power Supply is utilized for calibration of LISUN UV Lamp Spectroradiometer Test Systems. This UV spectrum calibration system comprises a deuterium-based UV standard light source and a dedicated power supply unit. Deuterium lamps produce a continuous spectrum, making them ideal UV reference sources for photometric analysis instrumentation. The integrated power supply ensures operational stability and extends the service life of the light source through precise electrical control.
