*1    Input source must be a stable light source
*2    Measure in normal mode with temperature 23±2 °C and relative humidity 50% or less
*3    Repeatability test is based on the status of shutter opening
*4    Input the 550nm monochromatic light and measure the stray light ratio at 550nm ± 40nm
*5    Testing condition: Sync mode at 60Hz. Sample speed depends on the measured sample. If the sample uses PWM, it will take longer
