  • High precision spectroscopy method
  • Wide dynamic range of luminance between 0.005cd/m² and 400,000 cd/m²
  • Wide spectrum range between 355nm and 835nm complies CIE recommendation
  • Unique optical design to reduce polarization error to <1% enables high precision testing of DUT having polarization property such as LCD.
  • High speed; 1 second for standard mode. 20msec for continuous mode
  • Wide luminance range without changing viewing angle.
     (0.005cd/m2 ~ 4,000cd/m2 at 2°)
  • Stable measurement of pulse drive light source and luminaries
  • Complies reporting format of CIECAM02 , Color Appearance Modelling for Color Management Systems)
  • Complies reporting format of CIE2000:2011, taking mesopic vision (Purkinje effect) into considered.
