The GMS-1000 glare measurement system adopts a high-precision imaging luminance meter. The high-precision measurement and analysis of the unified glare index UGR is realized through a precision electronically controlled pan/tilt and special measurement and control software. The measurement stability is good, the speed is fast, and the system is small in size and light in weight. . The system comes with a battery, no external power supply is required, and can be tested by connecting a USB cable to a computer.

1. Test glare based on imaging luminance meter
A high-precision imaging luminance meter is used to accurately measure the brightness of each point in the lighting scene, and calculate the glare index according to the theoretical formula.  
  2、 Multiple exposure technology, high sensitivity measurement, wide dynamic range
The brightness measurement is as low as 0.001cd/m2, and the multiple exposure technology is adopted to obtain high dynamic images (HDR), which can accurately measure indoor and outdoor environments .  
  3、 Low distortion and large field of view measurement
This system uses a precision pan-tilt to drive the multi-angle test of the imaging luminance meter, which eliminates the problem of high distortion when the fisheye lens measures a large field of view, and can achieve up to 2π full-space low-distortion luminance image measurement.  
  4、High resolution, high angle accuracy
Whether the acquired brightness image is close to the center of the field of view of the observation angle or the peripheral area, the high resolution and high angular accuracy are maintained, and the problem of low resolution around the fisheye lens is better avoided. 

 5、software function, meeting indoor and outdoor glare test requirements at the same time
It can realize the measurement of indoor and outdoor glare indicators such as TI, UGR, GR.
