Everfine GO-R5000 Full-Field Speed Goniophotometer

GO-R5000 Full-Field Speed Goniophotometer is a CIE C-λ type goniophotometer system with two mirrors and photometer detectors that can measure photometric and colorimetric parameters on C-plane or cone suefaces. During measurement the tested luminaires keep stable while the mirror and photometer detectors rotate around it, so the most steady specified lighting state of tested luminaire can be achieved.

Main Features:
•    Integrate multi goniophotometers in 1 facility by the multi detectors, it can realize near-field, quasi-far-field(optional) and far-field measurement as well as spatial luminance (optional) and colorimetric quantities measurement(optional).
•    Different relative spectral responsibity curves for different photometer detectors.
•    Super high stray light rejection performance.
•    Extremely wide dynamic range(100 times wider).
•    Half short the test distance in the dark room by the a second fixed mirror.
•    Fully meet the standard requirements of EN13032-1, CIE70, CIE84, CIE121 and IESNA LM-79,etc.
•    USA, Germany and China Patent Issued.
•    National High-Tech program (863 Program) Research Achievement.
•    Widely applied in NVLAP accredited labs.

Main Functions:
•    Photometric parameters test: Luminous intensity distribution curve, luminous intensity data, efficient light beam angle, isocandela diagram, isolux diagram, total luminous flux, zonal luminous flux, luminaires efficiency, utilization coefficient, maximum ratio of space to height, luminaire budgetary diagram, luminance limitation curves, glare grade etc.
•    The averaged and non-uniformity of colorimetric quantities and luminance can be obtained.
•    Electrical quantities: voltage, current, power, power factor, frequency, harmonics, etc.

GO-R5000 is widely applied for the measurement of luminous intensity distribution, total luminous flux, non-uniformity of luminance & colorimetric quantities and other photometric & colorimetric parameters of various type of luminaires and lamps, including street lights, indoor lights, flood lights, auto lights, signal lights, LEDs, halogen lamps, fluorescent lamps, HIDs etc. The test file can be export in GOS, CIE, CEN, IES, TM14, LDT, EUT format etc.
