SPD-380 Spectral Power Density Meter is an instrument specialized in measuring optical power density within the spectral range.

The system is designed especially for the determination of optical radiation hazard exposures specified in IEC 62471, such as actinic UV hazard exposure for the skin and eye, near-UV hazard exposure for the eye, retinal blue light hazard exposure, retinal thermal hazard exposure, thermal radiation hazard for eye and skin, for LED products, UV-Lamps, lighting sources, luminaires and etc.

In GMS-2200 Goniophotometer, the tested luminaire rotates only around the fixed vertical axis in the prescribed burning position and a reflecting mirror rotates around the horizontal axis, meanwhile, the mirror on rotating table in the opposite side rotates around the horizontal axis synchronously to pursuit the measuring beam reflected by the first mirror, and then reflect the measured beam perpendicularly towards to a fixed detector at the horizontal rotation axis. The combined motion of the luminaire and mirror permit the measurement of luminous intensity at the direction of any horizontal or vertical angle without titling the luminaire.

GMS-1600 goniophotometer is a type C goniophotometer used to measure the luminous intensity distribution, chromaticity uniformity and spatial spectrum distribution for LED lamp, PAR lamps, flush light panel and other small size lamps. The luminaire rotates around the vertical axis on its burning position while detector is rotating around the luminous center in the vertical plane. The goniophotometer has the advantages with fixed luminaire position, no mirrors in the optical ways, and less laboratory space occupied.

According to CIE IESNA National standards and other requirements require the use of rotating lamps to achieve multiple measurement methods such as B-β, A-α, and C-γ. Used for measuring the spatial light intensity distribution and various photometric parameters of indoor lighting fixtures, floodlights, and road lighting fixtures. Including: spatial light intensity distribution, light intensity distribution curve on any cross section can be displayed in rectangular coordinate system or polar coordinate system, spatial equal intensity curve, plane equal illuminance distribution curve, brightness limit curve, annular luminous flux, glare level, luminaire efficiency, effective luminous angle, upward light flux ratio, downward light flux ratio, total luminous flux of luminaire, effective luminous flux, utilization factor, as well as electrical parameters such as voltage, current, power, power factor, etc. It can work with double or single column.

GMS-3000 moving mirror goniophotometer with pursuit detector is one of the mirror goniophotometers recommended in ClE No. 70, and meets requirements of IESNA LM79. In this system, the position of tested luminaires is fixed and the mirror rotates around the photometric center of the tested luminaire. The pursuit detector and rotating barrier rotates synchronously with the mirror to ensure the light beam always be reflected into the detector perpendicularly and to eliminate the stray lights. The CCD spectrometer and photodetector installed in the center of the light trap could measure the spatial luminous intensity distribution, total flux and chromaticity uniformity of small size lamps. The pursuit detector and chromaticity measuring system are used to measure spatial intensity distribution of large size luminaires, narrow beam luminaires and high intensity indoor/outdoor luminaires and lamps, meeting the requirements of Energy Star, NVLAP, ERP, ESP.
