Precision Photometric Calibration System

The PRC-6M Precision Photometric Measurement System consists of an optical guide rail system, calibration equipment and tools. It is a photometric value traceability calibration system developed by LISUN for metrology institutes, third-party testing organizations, and photometric laboratories. It can perform verification and calibration of illuminance meters, luminance meters, illuminance probes, and light intensity standard lamps. It is the core hardware device for the metrological verification of photometric instruments.

The precision photometric measurement system offers multiple precision Photometric Bench in 2M/4M/6M sizes, equipped with multiple extinction apertures, multi-dimensional light source adjustment mechanisms, and coaxial rotary switching stations, effectively suppressing stray light and reducing optical path repetitive positioning errors. The measured values ​​are traceable to the SI candela standard, making it compatible with calibration services of EURAMET and ILAC accredited laboratories, and meeting the needs of instrument manufacturers for factory calibration and internal verification within enterprise laboratories.

System Configuration:

Notes:
1. The PRC-2M, PRC-4M, and PRC-6M use the same system configuration, differing only in the optical guide rail length, which is 2 m and 4 m respectively.
2. Darkroom and studio space requirements: Height 2 m, width 3 m, length = optical guide rail length + 2 m, for arranging the optical guide rail, calibration equipment and tools; the interior walls, ceiling, and floor must be painted with matte black paint, and the ambient temperature must meet the standard requirements.
3. The UV (200~400nm), NIR (800~1500nm) and Colorimetry calibration require optional calibration equipment and tools.
